FeatureSIn-office management of dentin hypersensitivity ........18
Once a diagnosis of dentin hypersensitivity has been made and depending on the etiology of the condition, treatment recommendations could include both in-office professionally applied treatments and at-home professionally dispensed treatments or recommendations for over-the counter treatments. No matter the treatment, it is important for the clinician to follow up with the patient to evaluate the therapeutic results.

Success in Whistler
The Denturist Association of Canada was hosted in Whistler May 25-29 by the
Denturist Association of British Columbia, a well-organized event encompassing many different facets of Denturism. DAC would like to thank the DABC for its hospitality and making our Annual General Meeting a great success.
Maria Green, our Treasurer and the President of B.C., along with Jason Kasper and our CAO Lynne Alfreds, went above and beyond providing a great convention. From managing a multitude of meetings, to the welcome wine tasting, golf tournament, education, dinner and dance, all of the activities were very well presented and enjoyed by all.
We were pleased to welcome the Provincial Regulators to this meeting. This was the first major face-to-face meeting of regulators since we had all met when we were working on internal trade some nine years ago.
Bill Lloy, Jennifer Roth, and Charles Gully have done a fantastic job organizing, coordinating, and facilitating the regulatory meeting. I highly commend Bill, Jennifer and Charles for embracing this monumental task, which was evident by the exceptional participation of the regulators.
The newly formed Canadian Federation of Denturist Regulators is the product of three days of intense meetings by our Regulatory Members. The members of
DAC are encouraged by the solidarity of the regulators and wish them well.
Our accreditation documents were ratified at the Curriculum Advisory Meeting (CAC) and at the DAC AGM; there are a number of Denturist educational faculties now ready to proceed with the new accreditation process.
Barb Peterson, our consultant and facilitator, has been superb in meeting all of our timelines, and in taking the time to understand Denturism and how it relates to the accreditation process. We would like to thank Barb for all of her guidance and persistence in helping us achieve our goals.
The George Connolly Award for Denturist of the Year was presented to Jamshid Zehtab-Jadid of Manitoba for his years of service as the Chair of Curriculum Advisory Committee and commitment to the profession. Congratulations, Jamshid for your outstanding effort and achievement.
Next year we are all invited to join Daniel Robichaud in Moncton, New Brunswick where Daniel will host the DAC AGM along with Canadian Federation of Denturist Regulators and New Brunswick annual meeting. Daniel has assured us there will be lots of fresh Atlantic lobster and a fun-filled down-east “kitchen party” atmosphere.
Elections for the executive were held and the following positions have been filled for the next two-year period: 1st Vice President, Paul Hrynchuk, Manitoba; 2nd
Vice President, Daniel Robichaud, New Brunswick; Vice President Administration, Benoit Talbot, Quebec (who is new to the board and the new president of ADQ); Vice President of Finance, Maria Green, British Columbia. I am honoured to have been elected as your president for my second term. I know this year will be busy as we continue with a number of our projects and I look forward to working with everyone.
This fall the International Federation of Denturists will be holding its annual general meeting in Helsinki Finland, September 15-18, co-hosted by the Finnish Denturist Association. I encourage all members to try to attend these international meetings. Future IFD meetings include England 2011 and Copenhagen, Denmark 2012.
The Denturist Association of Ontario has graciously agreed to host the 2012 DAC AGM as Perfecting Your Practice Conference to be held at Deerhurst Lodge in Huntsville, Ontario, exactly where the G8 was just held. I think our security will not be quite as rigorous as it was for the world’s leaders. Ontario’s PYP is one of the premier functions for education, networking with manufacturers, dental suppliers and fellow practitioners from all over the country.
As we progress to redefine, improve and expand our standards with a unified voice, we will inevitably guide Denturism to a prosperous future.
“The newly formed Canadian Federation of Denturist Regulators is the product of three days of intense meetings by our Regulatory
Members. The members of DAC are encouraged by the solidarity of the regulators and wish them well.”

Réussite à Whistler
L ’Association des denturologistes du Canada (ADC) a été l’hôte à Whistler,
du 25 au 29 mai, de l’Association des denturologistes de la Colombie-Britannique (DABC) pour la tenue d’un événement fort bien organisé portant sur de nombreux aspects de la denturologie. L’ADC aimerait remercier la DABC de son hospitalité et de sa contribution à faire de notre assemblée générale annuelle (AGA) une grande réussite.
Maria Green, notre trésorière et la présidente de la DABC, ainsi que Jason Kasper et notre directrice générale, Lynne Alfreds, ont fait preuve d’un dévouement exceptionnel pour nous offrir un congrès remarquable. De la gestion de multiples réunions à une dégustation de vin appréciée, en plus du tournoi de golf, de la formation, du souper et de la danse, toutes les activités étaient fort bien présentées et ont plu à tous les participants.
Nous étions ravis d’accueillir les organismes de réglementation provinciaux à ce rassemblement. C’était la première rencontre d’importance à se tenir, en personne, avec des représentants de ces autorités depuis
celle sur le commerce intérieur, qui a eu lieu il y a neuf ans environ.
Bill Lloy, Jennifer Roth et Charles Gully ont réussi de manière fantastique à organiser, coordonner et animer la réunion sur la réglementation. Je félicite très sincèrement Bill, Jennifer et Charles, qui ont accompli cette tâche monumentale avec brio, comme l’illustre la participation exceptionnelle des organismes de réglementation.
La Fédération canadienne des organismes de réglementation de la denturologie nouvellement créée est le résultat de trois jours de réunions intenses des membres de nos organismes de réglementation. Les membres de l’ADC sont encouragés de constater la solidarité dont ils font preuve et leur souhaite beaucoup de succès.
Nos documents d’agrément ont été ratifiés à la réunion du Comité consultatif des programmes d’études et à l’AGA de l’ADC; de nombreuses facultés de denturologie sont maintenant prêtes à appliquer le nouveau processus d’agrément.
Barb Peterson, consultante et animatrice de réunions, a accompli
un superbe travail. Respectant toutes nos échéances, elle a pris le temps de bien connaître la denturologie et son processus d’agrément. Nous aimerions remercier Barb de tous ses conseils et de sa persistance à nous aider en vue d’atteindre nos objectifs.
Le prix George Connolly du denturologiste de l’année a été décerné à Jamshid Zehtab-Jadid du Manitoba pour ses années de service à titre de président du Comité consultatif des programmes d’études et pour son engagement envers la profession. Félicitations Jamshid de vos efforts et de vos réalisations hors du commun.
L’an prochain, nous sommes tous invités à nous joindre à Daniel Robichaud à Moncton, au Nouveau-Brunswick, où Daniel sera l’hôte de l’AGA de l’ADC ainsi que de l’assemblée annuelle de la Fédération canadienne des organismes de réglementation de la denturologie et de la Société des denturologistes du Nouveau-Brunswick. Daniel nous a assurés qu’il y aura plein de homard frais de l’Atlantique et une belle ambiance de « party de cuisine » typique de l’est du pays.
Les élections à la direction ont eu lieu et les postes se répartissent comme suit pour
« La Fédération canadienne des organismes de réglementation de la denturologie nouvellement créée est le résultat de

beaucoup de succès. »

Our cOncern fOr the environment is more than just talk
As we continue to deliver valuable information through the pages of this magazine, in a printed format that is appealing, reader-friendly and not lost in the proliferation of electronic
messages that are bombarding our senses, we are also well aware of the need to be respectful of our environment. That is why we are committed to publishing the magazine in the most environmentally-friendly process possible. Here is what we mean:
We use lighter publication stock that consists of recycled paper provided by an fSc certified supplier. This forest Stewardship council (fSc) standard ensures that our paper comes from
efficiently managed forests with proper replanting programs that make this a reneWABLe and SuSTAInABLe resource.
Our computer-to-plate technology reduces the amount of chemistry required to create plates for the printing process. The resulting chemistry is neutralized to the extent that it can be safely discharged to the drain.
We use vegetable oil-based inks to print the magazine. This means that we are not using resource-depleting petroleum-based ink products and that the subsequent recycling of the paper in this magazine is
much more environment friendly.
During the printing process, we use a solvent recycling system that separates the water from the recovered solvents and leaves only about 5% residue. This results in reduced solvent usage, handling and hazardous hauling.
We ensure that an efficient recycling program is used for all printing plates and all waste paper.
Within the pages of each issue, we actively encourage our readers to reuSe and recYcLe.
In order to reduce our carbon footprint on the planet, we utilize a carbon offset program in conjunction with any air travel we undertake related to our publishing responsibilities for the magazine.
So enjoy this magazine...and keep thinking green.
Le mOt du PRéSident
une période de deux ans : 1er vice-président, Paul Hrynchuk, Manitoba; 2e vice-président, Daniel Robichaud, Nouveau-Brunswick; vice-président à l’administration, Benoît Talbot, Québec (nouveau membre du conseil et nouveau président de l’ADQ); vice-présidente aux finances, Maria Green, Colombie-Britannique. J’ai l’honneur d’avoir été élu président pour remplir un deuxième mandat. Je suis convaincu que nous serons très occupés cette année à poursuivre un certain nombre de nos projets et j’ai hâte de travailler avec chacun et chacune d’entre vous.
Cet automne, l’International Federation of Denturists (IFD) tiendra son
assemblée générale annuelle à Helsinki, en Finlande, du 15 au 18 septembre, et l’hôte conjoint sera la Finnish Denturist Association. J’encourage tous les membres à essayer de participer à ces assemblées internationales. Les futures assemblées de l’IFD auront lieu en Angleterre en 2011 et à Copenhague, au Danemark, en 2012.
La Denturist Association of Ontario (DAO) a bien voulu être l’hôte de l’AGA de l’ADC en 2012, pendant la tenue du congrès Perfecting Your Practice (Perfectionner sa pratique) au Deerhurst Lodge de Huntsville, en Ontario,
précisément là où le Sommet du G8 vient d’avoir lieu. Je pense que nos mesures de sécurité ne seront pas tout à fait aussi strictes qu’elles l’ont été pour les leaders mondiaux. Le congrès PYP en Ontario constituera une excellente occasion de formation et de réseautage avec les fabricants, les vendeurs de fournitures dentaires et les collègues praticiens de tout le pays.
À mesure que nous progresserons en vue de redéfinir, d’améliorer et de développer nos normes d’une voix unifiée, nous orienterons nécessairement la denturologie vers un avenir prospère.

Your voice, your resource
The DAC and DABC annual meeting in spectacular Whistler was a great
success and, of course, was a great opportunity to network with colleagues, socialize, and take in some excellent professional development and continuing education seminars. Thanks to all who worked so hard to make this event a success. The conference attendees numbered over 200 with representation from every province across the country. Look for more conference news on
page 25, and for information about the formation of a national registrar body in an upcoming issue.

Protect your retirement from disability
A critical illness can ruin retirement for many retirees. This is revealed in a special study by Health Services and Mental
Health Administration Health Reports published by Statistics Canada. Half of Canadian men and one-third of women, during their lifetime, will be diagnosed with cancer, a heart attack or a stroke. With the majority of Canadians being over 50, the chance of having a critical illness before age 75 is much greater than dying, and the majority of this group with recover. It is expected that seniors over 75 will make up half of the population by 2040.
Cancer is the highest cause of disability (27.2%). There has been a one per cent increase in the incidence of cancer every
year for the last 35 years. Currently, there are approximately
145,000 cases diagnosed annually.
Heart disease is the second highest for disability (26.6%). Every year, there are more than 70,000 heart attacks. Consider that 50 per cent of men and 30 per cent of women aged 40 and younger will develop coronary heart disease which often goes undetected until the occurrence of a disabling or lethal event.
Annually, 50,000 strokes occur among Canadians. The build-up of arterial plaque, coupled with high blood pressure, catches many off guard with this often imperceptible disease.
The survival factor. Many will survive a critical illness due to advanced medical technology – 75 per cent of those diagnosed with cancer will now recover and live more than five years. About 90 per cent of hospitalized heart attack victims survive the initial occurrence. After the first incidence of a stroke, 75 per cent survive. On average Canadian men live 8.5 years with some form of disability, and women 11 years.
What does Critical Illness Insurance (CI) cover? All critical illness insurance contracts cover the three main leading causes of illness: heart attack, cancer, and stroke. However, depending on the terms of the contract purchased, many other conditions may be covered, such as: coma, coronary bypass, Alzheimer’s disease, paralysis, and severe burns to name a few. Each insurance company will have different covered conditions, so it is important to research each carrier before purchasing a critical illness insurance.
How does Critical Illness Insurance compare to Long Term Care Insurance? Long term
care insurance is designed to pay for in-home or nursing home expenses associated with

chronic illnesses related to cognitive or motor impairment. If a person requires assistance with mobility, bathing, eating, dressing, or toileting, they would then become eligible for a Long Term Care Benefit that is usually paid on a monthly basis. Comparatively, a Critical Illness policy can provide immediate financial relief for you and your family. Such financial stability can help a person recover in dignity while being able to pay for any necessary medical treatment. The lump sum payment is usually paid 30 days after the diagnosis of a covered claim, and pays regardless of your ability to work.
Critical Illness Insurance protects your RRSP. With CI insurance, you will have an income source other than your retirement savings plans (RRSPs/RRIFs, etc). If a person had to cash in their RRSP, any income would become taxable in the year of withdrawal. For example, if a person required $100,000 to pay for medical treatment, non-covered drugs, living expenses, etc., they would have to withdraw at least $217,391 before taxes (assuming a 46% tax bracket). This amount would automatically place a person in the highest tax bracket in their province. All RRSP monies would become immediately taxable as income.
“Each insurance company will have different covered conditions, so it is important to research each carrier before
purchasing a critical illness insurance.”

Hiring the mini me
Is it really possible to find an employee who thinks exactly like you?
In a word, “no.” We all have a lifetime of varied, non-identical experiences that shape us and our thinking processes. Therefore, the chances of hiring your twin is not something you should count on.
Ideally, you should be looking for someone who is NOT a “mini you” but rather, someone who is somewhat your opposite number. I have a number of staff in my company who bring a lot of interesting background experience to our table and they think outside my box.
For a denture practice, you DO want a lab tech whose skills are up to your standards clinically speaking, but here again you may only find the diamond in the rough and you will need to train the person UP to your standards.
Finding the ideal candidate requires a number of steps in order to find as close a match to your requirements as possible.
What do you need?If you have no staff at all in your practice, you may want to consider hiring either a lab tech with great people skills who can handle reception as well and answer the phone. In the alternative, you could consider hiring a receptionist who can help in the lab part time. If you already have at least one staff member, you may need another pair if hands in the future. Make a thorough job description for the position, i.e. what exact duties do you want this position to cover.
Who are you looking for?You cannot find the ideal employee if you don’t know precisely what you are looking for. Define your ideal employee by writing down your wish list of characteristics. For
example, consider these points if you are hiring a receptionist:
1. What experience should they have? Have they every worked in a denturist or dental office? Or some other position where they had customer contact of some type?
2. What skills should they possess? Good and accurate typist? Computer software knowledge (ideally, the one you already have)? Bookkeeping? Excellent English, French or other language needed by your patient base?
3. What people skills and personality traits would you like? Terrific sounding on the phone? Well groomed and appropriately attired? Good work habits with initiative and ability to work alone? Problem solver? Creative ideas in terms of office procedure, protocols, advertising, etc.?
Good ability to take control of people and situations?
There is your wish list. Use it to tick the boxes for each candidate and see which ones most closely meet your requirements. This will help you be more objective in the hiring process.
Place the adPlace an ad in the local newspaper or on a website such as the government Jobbank.gc.ca which is free. Also consider other free websites, namely Craig’s List and Kijiji. On the free sites, you can have a longer, more detailed ad, whereas the newspaper ad will cost you per line so you may want to keep it short and sweet. In the ad, ask the candidates to fax or email their résumés to you.
16 Summer/ête 2010
Click here to return to the Table of Contents
Screen those résumésWhile a résumé is not the key to hiring an individual, the layout and presentation of it can reveal accuracy and neatness. The applicant either spent the time themselves to organize and put their résumé together or paid someone who knew how to do it properly. In either case, the individual knows that it is important to have a good presentation. The résumé should be reviewed and gaps in employment history looked for. These gaps are areas that you want to know about.
By screening résumés, you will narrow down the number of candidates to the serious contenders. Do a brief phone interview and listen to how they sound – bright, clear and personable? If yes, set up a live interview.
The interviewThe actual interview should provide you with the greatest amount of information. This is your opportunity to watch the individual perform under fire. This is your opportunity to see how they handle themselves, whether they can think on their feet, and whether they have the technical knowledge that the position needs.
(a) Results oriented? The primary point of interest must be whether the person is results oriented. You want someone who gets an idea, carries out the actions and produces a result. Ask the candidate to tell you what they have produced (accomplished) in their last job or two. Individuals who cannot tell you, or who tell you how their production could not be measured, are passed over. These are the clock watchers and people who feel they are paid for the time they put in, not for results. You don’t want these in your practice.
(b) Get referencesWithin 10 or 15 minutes you will know whether it is worth continuing with the interview. Those applicants who have produced results will know and will be very happy to tell you about them. They will also be able to supply the name of someone who can verify the actual production. Be
wary of those individuals who tell you about all the wonderful products they have produced but who cannot supply the name of anyone to verify it. Also, stay away from the individual who becomes very defensive about supplying names of people who will verify their production, or who challenge you for asking. They may not be telling you the whole truth.
(c) Technically qualified?If the applicant passes the above, you then want to ensure they have the technical qualifications needed. Ask them questions which demand a thorough understanding of the technical aspects of the position. Ask what they would do in certain situations which require a good technical understanding. This does not mean that they can actually DO the job but it does indicate that they, at least, have the knowledge.
(d) People oriented?If the position is one which requires dealing with patients, give them situations which test their skill, e.g. “What would you do if a patient complained about how high their bill was?”
(e) Meet your criteria?Do not waste your time with an applicant who does not meet the above criteria. Your time is valuable and you do not owe the person a lengthy interview for any reason. As soon as you see that they are not what you want, politely end the interview.
(f) They talk, you listenRemember to get the applicant to talk while you listen and observe. This is especially true if the position requires dealing with the public.
Check referencesReferences must be asked for and called, especially those who can verify the production of the candidate. While general references may or may not provide any useful information, production references will verify the truth of the statements. In any event, you want to obtain all possible information prior to hiring. When checking
references, ask about weaknesses or you may not be told about them. You can also ask if the person would hire them again.
Also, when looking for references, ask the individual to supply one for each place where they worked. A reluctance to provide a reference for a specific place may indicate a situation which you want to know more about.
Trial work day(s)Whenever possible, have the applicant or applicants come in and work in the practice for a day or two or three. This will provide you with an opportunity to verify how well they perform. You must remember that your practice and how things are done in it are new to them so they may not perform as well as you want during this short test. Nevertheless, it provides you with additional information which you can use when making your final decision.
Hire the bestAs objectively as possible, evaluate the candidates and pick the one who matches your wish list as closely as possible. The basic terms of employment should be put into a letter.
Trial periodIn most provinces there is a probationary period of three months when you can terminate the employment of new staff without notice or justification in any way and there is no severance pay required either. If your new staff member does not meet your wish list, do not feel guilty about letting them go. Move on and get the one you want. During this probationary period, most employees are on their best behaviour. So if anything is bothering you now, it may get worse after the three months, and then you are going to have to suffer with your mistake or pay to get out of it.
RememberThere is probably no “mini me” for you out there. What you ARE looking for is someone who brings new skills to your practice and enhances productivity and the quality of service to your patients. Good hunting!

IN-OFFICE MANAGEMENT OF DENTIN HYPERSENSITIVITY
Dentin hypersensitivity, also known as tooth sensitivity, root sensitivity, or just
sensitivity, is a common patient complaint. Patients describe the phenomena as sharp, short-lasting tooth pain irrespective of the stimulus (1). Holland and coworkers described dentin hypersensitivity as “characterized by short, sharp pain arising from exposed dentin in response to stimuli typically thermal, evaporative (air), tactile (rubbing), osmotic or chemical and which cannot be ascribed to any other form of dental defect of pathology” (2). Clinicians see dentin hypersensitivity as an exaggerated response to routine stimuli to the teeth. Patients respond to dentin
hypersensitivity when drying a tooth with an air spray or scratch a tooth with
the tip of an explorer. Some patients complain of pain when brushing
their teeth or flossing. Although it causes no direct harm to the
tooth, dentin or pulp, it has all the criteria to be considered
a true pain syndrome (3). It is important to
distinguish sensitivity pain from pain of
longer duration not treatable
with desensitizing agents that may be the result of pulpal inflammation (4). Frequently dentin hypersensitivity is triggered by tooth exposure to cold foods, sweets, beverages, or plaque accumulation on exposed root surfaces. Dentin hypersensitivity has been referred to as one of the most painful and least successfully treated chronic dental conditions of the teeth (5).
Once a diagnosis has been made and depending on the etiology of the condition, treatment recommendations could include both in-office professionally applied treatments and at-home professionally dispensed treatments or recommendations for over-the counter treatments (6). No matter the treatment, it is important for the clinician to follow up with the patient to evaluate the therapeutic results.
A number of studies have evaluated the prevalence of dentin hypersensitivity. The prevalence of dentinal hypersensitivity has been reported between 4% and 57% in the general population (7-10). Among periodontal patients, the frequency of tooth hypersensitivity is considerably higher (60%-98%) (11,12). Of interest, patients who have dentin hypersensitivity may not specifically seek treatment because they do not view it as a significant dental health problem but will mention it at a routine dental appointment (13). Both men and woman are affected by dentin hypersensitivity, although
women may be affected more often (14). Root sensitivity has been reported
on incisors, canines, premolars and molars although it has been reported to more often affect canines and premolars (15).
ETIOLOGY AND PHYSIOLOGY OF DENTINAL HYPERSENSITIVITYDentin is a porous, mineralized connective tissue with an organic matrix of collagenous proteins and an inorganic component, hydroxyapaptite. Dentin contains

a microscopic structure called dentinal tubules which are micro-canals that radiate outward through the dentin from the pulp cavity to the surface cementum border. These canals have different configurations and diameters in different teeth. For human dentin, one square millimeter of dentin can contain 30,000 tubules depending on depth. Each tubule contains a Tomes fiber (cytoplastic cell process) and an odontoblast that communicates with the pulp. Within the dentinal tubules there are two types of nerve fibers, myelinated (A-fibers) and unmyelinated (C-fibers) (16). The A-fibers are responsible for the sensation of dentinal hypersensitivity.
The most widely accepted mechanism of dentin sensitivity is the hydrodynamic theory, first described by Brännström (17). In this model, the aspiration of odontoblasts into the dentinal tubules as an immediate effect of physical stimuli applied to exposed dentin results in the outward flow of the tubular contents (dentinal fluids) through capillary action (Figure 1). The changes to the dentinal surface due to the physical stimulus lead to stimulation of the A-type nerve fibers surrounding the odontoblasts. For there to be a stimulus-response, the tubules must be open at both ends, at the dentinal interface and within the pulp. It has been reported that non-sensitive teeth fewer exposed dentinal tubules than sensitive teeth (18).
LOCATION OF DENTIN HYPERSENSITIVITYWhy are some root surfaces hypersensitive and others not? Patients are concerned whenever there is dental pain. While for some patients the discomfort of dentin hypersensitivity is only a minor problem, for others it is a constant condition that is typically a chronic painful episode that can lead to emotional distress. Patients can identify areas of dentin hypersensitivity before a clinical exam is performed. If dentin hypersensitivity is present during a clinical
examination through blowing air on a tooth or by scratching during a tactile exam of hard tooth surfaces but the patient has not described tooth sensitivity as a concern, there is no need to treat the condition. Treatment is generated by patient request after consultation.
Exposed root surfaces due to gingival recession are a major predisposing factor to dentinal root hypersensitivity (Figure 2) (14). Enamel loss with exposed dentin due to attrition and tooth wear due to bruxism, occlusal habits, and other forms of parafunctional activity can also contribute to the etiology of dentin hypersensitivity (Figure 3).
A study concluded that at least 22% of the adult population between 30 and 90 years of age will have evidence of recession in one or more teeth of 3 mm or more (19). The prevalence of root sensitivity has been reported as 9-23% before and 54-55% after periodontal therapy (scaling, and root planing, and periodontal surgery) (20).
Gingival recession is a predisposing factor to dentin hypersensitivity rather than a direct cause (14). With the root surfaces exposed to the oral environment, the dentin tubules must be opened at both ends, to the pulp and oral cavity, for a patient to have the symptoms of dentin hypersensitivity. In normal function, the tubules sclerose and become plugged. However, when dentin is cut or abraded,
The hydrodynamic theory describes the aspiration of odontoblasts into the dentinal tubules as an immediate effect of physical stimuli to exposed open ended tubules.

the mineralized matrix produces debris that spreads over the dentin surface to form a smear layer (24). This phenomenon occurs to both enamel and dentin, but the loss of this smear layer, the unplugging of the dentinal tubules contributes to dentinal hypersensitivity. Root surfaces exposed to the physical action of toothbrushing with and without toothpaste can be predisposing factors in removing the smear layer leaving a tooth hypersensitive (22). The opening of dentinal tubules can also occur due to poor oral hygiene techniques leaving bacterial plaque on root surfaces. The acidic byproducts of the plaque can open the dentinal tubules. Also, excellent oral hygiene techniques with highly abrasive dentifrices can cause continued dentinal tubule exposure. Another at-risk behaviour is the exposure of the oral cavity to acids, e.g., ingestion of acidic foods and beverages (23, 24), ingestion of chlorinated pool water (25), and bulimia and gastrointestinal reflux
disease can also contribute to the opening of the end of the dentinal tubules (26). Brushing immediately after ingesting acidic foods or beverages should be avoided.
SCREENING AND DIAGNOSIS OF DENTIN HYPERSENSITIVITYHow effective are dental professionals in the screening, diagnosis and treatment of dentin hypersensitivity? Unfortunately, dentists and dental hygienists do not routinely include screening for dentinal hypersensitivity unless the symptoms are brought to their attention by the patient (27).
A questionnaire mailed to 5000 dentists and 3000 dental hygienists in Canada to evaluate a practitioners’ understanding and clinical management of dentin hypersensitivity revealed some startling facts (27). Of the survey respondents, fewer than half considered a differential diagnosis, even though dentin hypersensitivity is by definition a diagnosis of exclusion. Many of those responding to the survey misidentified the etiology with 64% of the dentists and 77% of the hygienists identifying bruxism and malocclusion as triggers of dentin hypersensitivity even though there is no evidence that these have identified as a major cause. More troubling is that only 7% of dentists and 5% of dental hygienists correctly identified erosion as a primary cause of dentin hypersensitivity. Further, 17% of dentists and 48% of hygienists were not able to identify the accepted theory of hypersensitivity.
In this same survey, the management of dentin hypersensitivity was evaluated. Only half of the respondents to the survey on hypersensitivity had the confidence to manage a patient’s pain with only 50% considering the modification of predisposing factors to control a patient’s pain. This survey also demonstrated a lack of understanding for the mechanisms for desensitizing teeth with desensitizing toothpastes. The lack of knowledge on the action and treatment of dentinal hypersensitivity was demonstrated when most dentists (56%) and dental hygienists (68%) believed desensitizing toothpastes helped prevent dentin hypersensitivity while 31% of dentists and 16% of hygienists did not believe

desensitizing toothpastes relieved dentin hypersensitivity.
Dental professionals need to be better educated on the etiology and treatment of dentin hypersensitivity. As part of any screening for dentin hypersensitivity, the clinician should assess whether there is a localized or generalized problem. Localized isolated tooth dentin hypersensitivity can usually be treated with in-office treatments. For generalized conditions where there is significant recession on multiple teeth, an at-home treatment regimen may be a better choice.
TREATMENT OF DENTINAL HYPERSENSITIVITYOnce the diagnosis of dentinal hypersensitivity has been made and the etiologic factors identified, a treatment plan can be developed and implemented (27) (Table 1).
Drisko summarized preventive recommendations for dentinal hypersensitivity (28).• Suggestions for patients:- Avoid gingival recession due to poor
plaque removal.- Avoid using large amounts of dentifrice
or reapplying it during brushing.- Avoid hard bristle toothbrushes.- Avoid brushing teeth immediately after
the ingestion of acidic foods.- Avoid overbrushing with excessive
pressure or for an extended period of time.
- Avoid excessive flossing or improper use of other interproximal cleaning devices.
- Avoid picking or scratching at the gumline or using toothpicks inappropriately.
• Suggestions for professionals:- Avoid over instrumenting the root
surfaces during scaling and root planing, particularly in the cervical area of the tooth.
- Avoid over polishing exposed dentin during stain removal.
- Avoid violating the biologic width during restoration placement as this may cause recession.
- Avoid burning the gingival tissues during in-office bleaching and advise patients to be careful when using home bleaching products.
OVER-THE-COUNTER DESENSITIZING TOOTHPASTESRoot sensitivity is well recognized by the general population as an oral condition that they can treat themselves. Over-the-counter (OTC) treatments for sensitive teeth, usually in the form of toothpastes are a major category of dentifrice. Since the use of an OTC product can be the most cost effective means for a patient to receive care, many people make the decision to self medicate with desensitizing toothpastes.
What are desensitizing toothpastes and do they work? Dentifrices claiming a desensitization effect come under scrutiny from the U.S. Federal Drug Administration. The claim of desensitizing teeth is a therapeutic claim that must be substantiated by either clinical trials or the addition of an ingredient to the toothpaste that is recognized as being an effective,
active agent for the treatment of the condition listed. The most popular ingredient for desensitizing in toothpastes is potassium nitrate. According to the FDA monograph, for a toothpaste to claim to be desensitizing, it needs to contain 5% potassium nitrate (29). The mode of action of a 5% potassium nitrate has been described as a penetration of the potassium ions through the tubules to the A-fibers of the nerves decreasing the excitability of these nerves (30, 31).
PROFESSIONAL IN-OFFICE TREATMENT OF DENTINAL HYPERSENSITIVITYSince gingival recession and exposed root surfaces are major predisposing factors to dentin hypersensitivity, gingival grafts should be considered as part of a treatment plan, particularly when the recession is progressive, there are aesthetic concerns, or the sensitivity is unresponsive to more conservative treatment (32, 33). When the exposed sensitive root surface has surface loss due to abrasion, erosion, and/or abfraction leaving a notching of the root, consideration should be given to placing either an adhesive composite resin or glass ionomer restoration (34). These restorations will both restore the tooth to full contour and seal the exposed and open dentinal tubules.
Another major dentin hypersensitivity issue is the patient having a scaling and/or root planing and a dental prophylaxis. In many cases after a dental cleaning, the dentin hypersensitivity is heightened. For these patients rapid, immediate relief is desired. Recently, Colgate introduced desensitizing paste, Colgate Sensitive

Pro-relief for in-office application to reduce post-operative dentin hypersensitivity after routine dental cleanings. This new in-office desensitizing paste contains 8% arginine and calcium carbonate. The mode of action mimics the chemical reactivity of saliva in carrying calcium and phosphate ions for deposition on the dentin and root surfaces gradually causing open dentinal tubule occlusion. The mix of arginine and calcium carbonate work synergistically with the calcium and phosphate in the oral environment using a similar mode of action to that of saliva but in a significantly more rapid deposition and effective clogging of the tubules. This results in the creation of a dentin plug that resists normal pulpal pressures and acid attack leading to a desensitizing effect. Two studies have demonstrated that application of this desensitizing paste prior to a professional dental cleaning was effective in providing patients with relief from the active treatment over a period of four weeks after scaling and root planing (35), and was effective as a sensitivity preventive applied prior to a dental prophylaxis (36). This novel desensitizing formulation provided
statistically significant reductions in dental hypersensitivity following the procedure when compared to the control.
In-office paint-on surface treatments are a more popular approach to treating root hypersensitivity (Table 2). These are especially effective when localized conditions (single teeth) demonstrate dentin hypersensitivity. A variety of products have been reported to be used to successfully reduce dentinal hypersensitivity. These products generally occlude and seal the dentin tubules. Resin-based materials have been reported to successfully reduce dentin hypersensitivity (37, 38). With the expanded use of fluoride varnish, they have become more popular to seal exposed root surfaces and reduce hypersensitivity. Use of a 5% sodium fluoride varnish painted over exposed root surfaces has been shown to be an effective treatment of dentin hypersensitivity (39). An aqueous solution of glutaraldehyde and HEMA (hydroxyethylmethacrylate) e.g., Gluma Desensitizer (Hereaus-Kulzer) and Calm-It (Dentsply-Caulk), has been reported to be an effective desensitizing agent for up to nine months (38, 40). The mechanism for tubule occlusion appears to be due to the glutaraldehyde effects (41).
Using paint-on desensitizers is an excellent treatment of individual teeth. The clinical technique for the use glutaraldehyde desensitizers requires the tooth be clean and dry (Figure 4). Since the tooth is sensitive, dry the tooth using a blotting technique with a cotton roll (Figure 5). For
the Calm-It desensitizer, it is recommended that the desensitizing liquid be applied for 30-60 seconds using a gentle rubbing motion keeping the root surfaces wetted with the desensitizing agent (Figure 6). After application, using a very gentle air spray, blow off most of the excess but leave the surface wet (Figure 7). Using the air spray will demonstrate to the patient that there is a reduction in sensitivity. For most patients, I have them continue using a desensitizing toothpaste for the next month. Glutaraldehyde desensitizing agents have also been shown to help reduce postoperative sensitivity with composite resin restorations that have used etch and rinse (total etch) adhesives. After etching, rinsing and drying, the glutaraldehyde desensitizer is applied for 30-60 seconds with gentle rubbing, dried from the cavity preparation and the adhesive applied before the composite restoration. Glutaraldehyde desensitizers can also be used with glass ionomer restorations.
Other techniques include paint-on oxalate-based desensitizers and lasers. The use of oxalates for the treatment of dentin hypersensitivity has been shown to be effective (4, 42). The oxalate precipitates on the open dentinal tubules occluding them. This action reduces patient perception of pain to external stimuli. An oxalate desensitizer with potassium nitrate (D/Sense, Centrix, Shelton, CT) has been shown to be an effective desensitizer (42). This product occludes open dentinal tubules combined with the desensitizing effect of

potassium nitrate. Oxalate desensitizers are not compatible with resin or glass ionomer adhesive techniques. Lasers have also been used successfully to seal open dentinal tubules either by themselves or with surface treatments with other materials (43, 44).
Recommendations for in-office techniques and indications for their use are product specific. The clinician needs to understand the different techniques before employing them in the treatment of dentin hypersensitivity for their patients. There will be times a restorative intervention will be necessary. When the root surface is exposed with the presence of notching, the depth and size of the notching will in some cases require the placement of a restoration (34).
Dentin hypersensitivity has also been reported as a post operative symptom following restorative treatment. This sensitivity is usually associated with routine fixed prosthodontic treatment during preparation, impressions, and temporization. In fact most astringidents used for gingival retraction are acidic and remove the smear layer leaving open dentinal tubules. Postoperative sensitivity after the placement of posterior composite resins is the same as dentinal hypersensitivity. Preventive treatment to avoid having postoperative sensitivity would involve using the same paint-on desensitizing agents used for the treatment of exposed root surfaces.
CONCLUSIONDental professionals need to understand the causes of dentin hypersensitivity. A patient should be evaluated based upon risk factors that may be present. Once a diagnosis has been made and the factors have been identified a treatment plan can be outlined to the patient for the treatment of dentin hypersensitivity. As part of the routine dental examination, dental professionals should include in their patient questions during every recall appointment whether there are any sensitive teeth. Depending on severity of the condition clinical management of dentin hypersensitivity may include both in-office and self-applied at-home therapies. In most circumstances, the least invasive, most cost-effective treatment is to use an effective desensitizing toothpaste. For individual hypersensitive teeth, an in-office
treatment can provide the patient with pain relief. Once a tooth is predisposed to dentin hypersensitivity it will need to be reevaluated for continued at-home treatment.

2010 DaBC Convention & DaC annual meeting reviewThe DAC AGM was held in conjunction with the Denturist Association of BC’s 2010 Convention at Whistler, BC. The Westin Resort & Spa was a perfect setting for a very successful event.
The DAC AGM was timed so that delegates could participate in the DABC Annual Golf Tournament; luckily that day the rain chose to hold off and the 50+ golfers had a wonderful game at the Whistler Golf Course. The rain came down as the BBQ began that evening and continued to fall lightly for the duration of the convention. It didn’t stop registrants from trying out the zip lines, mountain biking or taking a stroll through Whistler Village, though. Having watched the 2010 Olympics we all know how unpredictable BC weather is!
The sad news was announced that the wife of one of our denturists from Nova Scotia had been badly hurt in a bike riding accident in Vancouver was met with a flurry of support as the provincial associations and many denturists pledged money to send to the family to aid in her recovery and help to offset the costs
of the family staying in a city so far from home. We are happy to report that the MacDonalds are now back home and Debbie is recovering with her family and friends around her. We wish her and Greg all the best as she works towards recovery.
The gala event on Friday night was fantastic. The seafood buffet was simply the best!
The Dentsply Denturist Association of Canada Denturist of the Year Award was presented by Tom Robinson of Dentsply and Michael Vout, President of DAC, to Jamshid Zehtab-Jadid from Manitoba. Jamshid was honoured for his tireless efforts as Chair of the Curriculum Advisory Committee. Congratulations Jamshid, you deserve this honour!
Congratulations also go to James Connolly for being honoured by the Denturist Association of BC with the Ivoclar Vivadent Hall of Fame Award for dedication and contribution to the profession, and to Paul Biddle who was presented with the DABC Denturist of the Year Award for his work on the Executive Committee.
• The DAC Accreditation Documents were finalized and presented to the delegates at the DAC AGM. The newly formed Canadian Federation of Denturist Regulators (CFDR) will now take the documents for review until the end of August.
• Paul Hrynchuk, Chair of the Procedure Code Committee, presented the DAC Procedure Code Guide with updated definitions and it was approved by the delegates, any changes or additions must be requested by the end of August for the following year.
• It was agreed that the Special Project Fees to the Provincial Associations will be suspended for 2011 and will be reviewed annually.

he dental laboratory world is undergoing dramatic and rapid changes in the crown and bridge arena. The days of mixing
plaster are numbered as more and more dentists are now using intraoral scanners in lieu of impression material and then exporting these images to the dental labs. When the lab receives the file, they have a couple of options. Taking the more traditional route, the lab can create a model using a variety of CAD/CAM processes. A model can be milled from a block of acrylic or it can be created by STL (stereolithography) by a 3D printer. These milling/STL units can be quite expensive so many labs are sending the files out for processing. This has a fee attached to it, but what comes back is an extremely accurate and durable model, with dies already cut and trimmed. The beauty of this model is that the margins will not chip even if repetitive waxing and try-ins are done and the contacts remain untouched and un-scraped. The results are perfectly fitting castings, with excellent margins and perfect contacts. The occlusion is usually taken as a centric bite, so there may be some minor adjustments necessary in excursions.
If the lab has invested in computers and software, there may be no reason to create a model at all. The digital impression file appears on the computer monitor and the technician can virtually design and wax the case on the screen. This has been done for 25 years with the CEREC system. The dentist does the design on the computer
monitor, and sends that to an in-office milling center. The crown or partial coverage restoration is made from a block of ceramic or composite. This is a problem for some dentists. First of all, it takes time to design these restorations (although newer software makes this quite simple) and there are only a limited number of materials that can be milled in the office, and most are not as strong as similar restorations made in a lab and fired in an oven. There is a new block of EMax that does allow the dentist to mill in the office and fire in his or her own oven. This adds time and expense but seems to create a much more robust restoration. The shift is on to export those digital impressions, including CEREC (and E4D) to a lab for processing instead of doing it in-house. Some dentists have not found the cost savings doing it themselves to outweigh the time and training required to do their own design and build.
There are some other options opening up. The dentist can get a tabletop impression scanner. This allows the dentist to take a traditional impression, put it in the box and get a file that can be exported to the lab for processing as above. No model has to be made. There is no issue of plaster expansion and altering casting techniques to accommodate these discrepancies. There are, of course, more robust impression scanners available to the dental lab. If that course is taken, the laboratory can offer a totally digital service to the dentist or in the case of denturists, to the patient.

Several labs are now offering a model-less service at a reduced fee. Thus the restoration comes to the office in little box. This is a difficult shift for many dentists. There has to be a great leap of faith to get rid of the model. What, though, does this mean to the lab? In a large facility there is a reduction in the work force of model people, waxers and casters. The lab owners are ecstatic – the lab techs are starting to sweat.
So what about the world of removable prosthetics? So far full dentures are still easily and affordably constructed “the old way.” It is not possible yet to get a good digital impression of soft tissue for numerous reasons. However, in the world of partial dentures with cast frameworks, digital is here. The traditional impression is created, but then scanned. One revolutionary company from Massachusetts has come up with a virtual waxing system that can easily and accurately create a castable pattern, all done on the computer. The company is Sensable (www.sensable.com) and has been developing for over two years with remarkable results. The technician uses a mouse-like probe to wax on the screen. Due to a clever use of what is called Haptic Technology, the technician can actually feel the contours of the teeth and tissues. Once the waxup is designed, this pattern is sent to a computer to be printed (STL) and a castable frame is ready to go. Or the digital file could be sent to a CAD machine that would mill it out of a block of metal.
Luckily, there is time. The dentists have been very slow to purchase the intraoral scanners, and fewer have gotten the impression scanners. This does open up an opportunity for the dental lab. By getting one of these scanners and purchasing or
setting up an alliance with labs that have digital setups, the lab can promote itself as state-of-the-art, using digital technology.

industry merger creates one of the 10 largest global dental equipment manufacturers
SciCan, a Toronto based manufacturer of infection control products and
solutions with subsidiaries in Canonsburg PA, Augsburg, Germany, and Zug, Switzerland has merged with dental manufacturer SycoTec (previously, EWL, a subsidiary of the KAVO Group located in Leutkirch, Germany) and French endodontic specialist MICRO-MEGA (Besançon). SciCan, the world’s largest producer of table-top autoclaves, will be part of this company alliance under the leadership of SycoTec’s Managing Partner Dr. Martin Rickert. Together the group will be one of the 10 largest dental equipment manufacturers in the world of innovative products for the dental and medical markets.
“We can now offer clinical instruments, drives and infection control solutions, all from one source,” Dr. Martin Rickert announced. The three companies are being integrated under one common umbrella, but will remain independent. It is not a buy-out; hence no purchasing price was paid. Merger-related downsizing is not intended.
SciCan will be part of a strong dental, medical and technology group, owned by Arthur Zwingenberger, Chairman of SciCan and Dr. Martin Rickert, Managing Partner of SycoTec. The group will be managed by Dr. Martin Rickert as Executive Chairman who will follow a management model that maintains independence within the individual companies under the group’s administrative and strategic umbrella. The main principle behind the new structure is to make decisions where they actually occur, a concept which will be applied to SciCan as well. Although the family-owned enterprise with its headquarters in
Toronto (Ontario) is being merged with the two European companies, SciCan and its brands will remain in their present form. SciCan’s Chairman Arthur Zwingenberger will serve as Chairman of the new group.
“The name of the group is being discussed in-house for now,” said Dr. Martin Rickert, who points out that most of the positions within the organization will be filled
with existing personnel, to avoid creating unnecessary costs. “Much more important for us than finding a name was being able to handle the operational synergies so that we could focus on our shared opportunities as quickly as possible.”
While SycoTec concentrates mainly on drives, and specialized motors, MICRO-MEGA manufactures top-quality root canal instruments and hand pieces which are commonly used in every dental office. SciCan complements this range of products with critical procedures before and after treatment: namely infection control practices which include washing, disinfection and sterilization. “It becomes more and more important,” says Rickert. “Bacteria has to be removed from all the instruments that were used, for the doctor to safely work with them again. The legal guidelines in this regard are getting more stringent.” SciCan comes at the right time: The Canadians produce a full range of infection control products – on the one hand autoclaves (sterilizing units), and on the other, state-of-the-art cleaning and disinfection technologies which are sold in both dental and medical markets. The consumable products for infection control complete the range.

DENTSPLY Canada has expanded its diagnostic impression product offering to include Algin·X™ Ultra Alginate Alternative.
New VPS-based Algin·X™ Ultra is the ideal alternative to alginates whenever you need convenience, flexibility, ease and speed. The use of Algin·X Ultra Alginate Alternative Material allows immediate pouring in the office following disinfection, or the option of delayed and/or repeated pours, without sacrificing accuracy. Automix cartridges provide a homogenous, consistent mix every time and save dispensing and clean-up steps when compared to traditional alginates. Algin·X Ultra is available in 50ml cartridges and DECA™ 380ml cartridges for dynamic mixing machines.
As the alginate alternative from the makers of Jeltrate®, the #1 alginate, Algin·X™ Ultra Alginate Alternative is the option you can rely on for diagnostic impressions.
For more information, please contact DENTSPLY Canada at 800-263-1437, visit www.dentsply.ca or call an authorized DENTSPLY Distributor.

tHe un-COmFORt ZOneby Robert Wilson
The Secret for people who don’t believe in voodoo
T he latest fad in motivation is the Law of Attraction, or more popularly The
Secret, after the motion picture and book by Rhonda Byrne. The idea being that if you use the power of The Secret you will attract health, wealth and friends to you in abundance.
The Secret takes an old idea and repackages it for today’s society. The core idea is that your thoughts control the world around you. If you have positive thoughts, good things come your way. If you have negative thoughts then bad things come your way. In other words, if you wish hard enough for the things you want – you will get them. Simple. Or is it? If it were simple, then countless people throughout history would have figured it out over and over, and it would not be much of a secret. Perhaps it takes a little more effort than suggested, or perhaps it is just a pipe dream.
We, as modern educated people,
need more proof. In order to make it palatable to the skeptic in us, The Secret adds an element of science. We are told that quantum physics has identified that all things at the sub-atomic level exist as both particles and as waves – constantly shifting between being solid matter and being pure energy. It is then proposed that our thoughts create brain waves which in turn influence the sub-atomic waves of the entire universe. The Secret claims that the more intent you are in your wish the faster the universe will act upon it. Is it real, or is it voodoo science?
If real, it sounds wonderful. Now, if I understand correctly, if I wish real hard I can become a concert pianist and play to a sold out audience in Carnegie Hall? I only see one hitch: I’ve never had a piano lesson in my life.
The Secret also presents the Law of Attraction as if it had been intentionally kept hidden for centuries. That it
was suppressed and held by a few conspirators so that they could control all the wealth of the world. Unfortunately, that notion is nothing other than a marketing ploy to generate interest in the book. It also contradicts the concept of Law of Attraction. The idea that a select group of people have kept it away from the masses intentionally preys on the destructively negative emotion of envy.
To the contrary, people who have understood the Law of Attraction have made numerous attempts at sharing it with the world at large. The best example is Andrew Carnegie, who was one of the most successful so-called “Robber Barons” of the Industrial Age. Carnegie hired Napoleon Hill to research the most successful people in the world, how they got that way, and then record his findings in a book. The book is Think and Grow Rich and was published in 1937.
The best thing about Think and Grow

tHe un-COmFORt ZOne
Rich is that it takes the mysticism out of the Law of Attraction. So, for those of you who find wishing on a star a bit difficult to swallow as a method for acquiring wealth, here is the real secret:
Identify your goal. Make a written plan to acquire that goal. Work your plan persistently. Give it your time, attention and energy. The more time and effort you give, the quicker you will achieve it. Visualize it coming to fruition. Draw it, illustrate it, photograph it, then keep it in front of you. Revise your plan as your knowledge grows. Be open-minded to opportunities that arise that may deviate from your plan, but still move you toward your goal.
The world’s most successful people were extremely focused on achieving one goal. They focused to the exclusion of everything else including family, friends, lovers, recreation, entertainment, vacations and hobbies.
Next, tell everyone you know about your goal. Spread the word, so that people who can assist you are aware of your intentions. I truly believe that positive-minded people attract more opportunities to themselves because they are so pleasant to deal with.
The formula is simple, but most of us compromise our goals because we want to enjoy a full balanced life. A life filled with friends, family and good times. We focus on our goals when time allows, and in turn, our goals take much longer to achieve. The true secret is staying focused on your goal.
