Definition:RAMFJORD(1966):Bruxism is the habitual
grinding of teeth when the individual is not chewing or swallowing.
Rubina(1986):Bruxism is the term used to indicate non-function contact of teeth which may include clenching,gnashing and tapping of teeth
BRUXISM

Etiology:• The etiology of bruxomania could be from certain
definite cortical lesions.• A tendency to gnash and grind the teeth has been
seen associated with the feelings of anger and aggression.
• Occlusal discrepancies-Improper interdigitation of teeth may lead to bruxism.
• Mg++ deficiency has been reported as an etiological cause for bruxism and has treated several cases with therapeutic doses.
• Allergies have also been related to noctural bruxism.
• An overenthusiastic student over achievers may also develop the habit.

Management:1. Occlusal adjustment-• This would result in immediate disappearance of habitual
grinding of teeth.• Any prematurities or occlusal interference in restorations
should be able to withstand the forces of bruxism.• Cronoplasty plays an important role in occlusal treatment.• However extensive occlusal adjustments are
contraindicated.• Before any occlusal adjustments are done the muscles
should be brought back to a relaxed position to allow the jaw to resume its normal physiologic movements

2.Occlusal splints: • Vulcantic splints have been recommended to cover
the occlusal surfaces of all the teeth as a treatment for bruxism.
• A reduction in the increase muscle tone is observed with its use.
• In the case of children the use of a soft splint is advisable.
• The splint is made on the mandibular models using dental bioplast material.
• Little adjustment is required in children where intercuspation is less.

3.Restorative treatment:• If the abrasion is so severe that penetration into
the pulp chamber is imminent,pulpal therapy with full coverage stainless steel crowns is indicated.
4.Psychotherapy:• Counselling the patient can lead to a decrease in
tension and also create a habit awareness.• This may result in an increase in voluntary
control that can lead to reduced tooth para functions.
![Page 12: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/12.jpg)
• Behavioral modality is initiated by the dentist through explanation and arousal of the patient’s awareness of the habit.
5.Relaxation training:• In this technique,the patient is instructed to
tense the muscle group in consideration and relax ,thereby training the patient to relax the muscle group voluntarily.
• Hypnosis,conditioning,etc.,are also indicated for subjects in whom bruxism is due to central cause.

6.Physical therapy:• If musculoskeletal pain and stiffness are associated
with bruxism,a brief course of physical therapy is appropriate.
7.Drugs:• Vapo coolants such as ethylchloride for pain within
the TMJ area,local anaesthetic injections directly into the TMJ or into the muscles,tranquilizers,sedatives and muscle relaxants are used
• Placebo may be used to rule out the psychological etiology
![Page 15: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/15.jpg)
• Medications can be prescribed for few days to alter the sleep arousal and anxiety level,eg.,diazepam.
• Low doses of tricyclic antidepressants may be used to inhibit the amount of REM sleep.
8.Biofeedback:• This is a technique that utilizes postive feeback to
enable the patient to learn tension reduction.• It is accomplished by allowing the patient to view
an EMG monitor, while the mandible is postured with a minium of activity.

9.Electrical method:• Electrogalvanic stimulation for muscle relaxation is
currently being utilized for treatment of bruxism.
10.Acupuncture technique for muscle relaxation :• They are under evaluation
11.Orthodontic corrections:• Malocclusions such as classII and classIII
relation,frontal open bite and crossbite when associated with functional malocclusion may create a predisposition to bruxism.

LIP BITINGDEFINITION:Lip biting:Habits that involves manipulation of the
lips and peri-oral structures are termed as lip habits.
CLASSIFICATION:Wetting the lip with the tongue.Pulling the lips into the mouth between the
teeth(Schneider,1982)
![Page 19: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/19.jpg)
LIP BITING
![Page 20: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/20.jpg)
ETIOLOGY:1) Malocclusion2) Habits 3) Emotional stress
Management of lip biting:Lip habit is non-self correcting and may become more deleterious with age,because of muscular forces interacting with the child’s grown.Treatment of a lip habits should be directed initially towards the etiology of the habit.
![Page 21: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/21.jpg)
1.CORRECTION OF MALOCCLUSION:• If there is a classII division I malocclusion or an excessive
overjet problem,the abnormal lip activty may be adaptive to the dentoalveolar morphology.
• In such cases it is deemed wise to correct the malocclusion before onto break the habit.
• ClassI malocclusion with increased overjet fixed or removable appliance to tip the teeth back.
• ClassII growth modification procedures to treat the malocclusal.
• If the child has an uncrowded early mixed dentition and activator may be placed in an attempt to reposition the maxilla to the mandible in a favorable position and allow the child to effect a more normal lip seal.
![Page 22: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/22.jpg)
2. Treating the primary habit:• The lip habit along with digit sucking can be corrected by
aligning the dental arch using hawley’s retainer with a labial bow,which can be used to retract the maxillary incisors and an acrylic plate can be used as a habit reminder.
3.Appliance therapy:• Oral shield is also an useful appliance classI malocclusion • It helps to stop the habit and also incisal alignment.
![Page 23: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/23.jpg)
• The additional to a small loop to the labial oral shield improves the lip tonus by helping in lip exercise.
• Performed for 10 minutes , 3times a day.
![Page 24: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/24.jpg)
Lip bumper• A lip bumper may be used as an adjunctive therapy
in both comprehensive and interceptive treatment regimens.
• The lip bumper is positioned in the vestibular of the mandibular arch and serves a prohibit the lip from exerting excessive force on the mandibular incisors and to reposition the lips away from the lingual aspect of the maxillary incisors
• This enables the distal repositioning of the maxillary incisor resulting in a decrease overjet and overbite.
![Page 25: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/25.jpg)
• Either the second deciduous molars are the first permanent molars are banded and the buccal tuber and soldered to them
• The labial screen assembly may be either soldered to the band or crowns or slipped into the buccal tubes.
• The labial shield keeps the wire away from the lower incisor, preventing it from cushioning to the lingual of the maxillary incisor during posture functioning.
• With no labial restraining lip habit, the tongue will then stimulate the lower incisors to move labially,which increases the arch length, reduces crowding and excessive overjet.

Masochistic habits
It is a self-injurious habits are those in which the patient enjoys inflicting damage to himself.It is rare in normal children but is mostly seen in mentally retarted children.(10-20%) and children with psychological abnormalities.
DEFINITION:Receptive acts that result in physical damage to the individual.This habits show an increased incidence in the mentally retarted population.
![Page 28: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/28.jpg)
Etiology:The etiology may either be :-a. Organic:Syndromes and syndrome like maladies such as lesch-nyhan disease and de lang’s syndrome In which symptom such as repetitive lip,finger,tongue,knee and shoulder biting are commonb. Functional:This can be further divided into-• Type A-this are injuries superimposed on a pre-
existing lesion.eg.,a child with a finger nail finger habit is under treatment for a skin lesion.
![Page 29: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/29.jpg)
• Type B:The self-injurious habit may exacerbate the feature existing due to a primary habit.eg.,rotation of the thumb while thumb sucking can harm the soft tissue.
• Type C:They may be injurious of unknown or complex etiology.This type of behavior has a greater psychological component.There may be multiplicity of symptoms of greater intensity.

Management :-They are initiated by=1) Pharmacological 2) Psychological3) Physical restraints4) Palliative treatment5) Mechano therapy
![Page 31: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/31.jpg)
1) Pharmacological method• Most of the existing literature or pharmacological
treatment of SIB has adressed the postulaTed defects in the dopaminergic ,opiate or serotonin system.
• But there are disadvantages to pharmacologic treatment as it usually requires chronic use of drugs and this agents often places patience in a chronic stupor.
![Page 32: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/32.jpg)
2)Psychological treatment• Some children experience a feeling of
neglect,abandonment and loneliness and through the use of self-injurious behavior attempt to solicit attention and love .
• Treatment of self-injurious behavior generally requires a multi-disciplinary approach.
• Care should be taken in dealing with this form of behavior because of the underlying emotional component.
• Continued concerned for the habit may support or reinforce the habit.
![Page 33: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/33.jpg)
3)Physical restraints• Restraint may be reliable means of preventing
injury of the SIB-affected individual,physical restraints include mitten’s,arm,borders,facial masks,helmets and restrictive clothing,but requires constant wear if they are to be successful.
![Page 34: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/34.jpg)
4)Palliative treatment
• Adjunctive therapy in the form of bandages for any oral ulcerations will help in healing of the wound as well as a habit reminder
![Page 35: MANAGEMENT OF BRUXISM, LIP BITING AND MASOCHISTIC HABITS](https://reader035.vdocuments.net/reader035/viewer/2022081507/587f5c6a1a28ab0d378b7763/html5/thumbnails/35.jpg)
5)Mechano therapy
• Oral shield will also determine the child from the unconcious continuation of the habit.
• Treatment for self-multilation may also include use of restraints protective padding.

Bobby pin opening• Usually seen in teenage girls where is opening
bobby pin with anterior incisors is done.• Clinically we see notched incisors and partly
denuded labial enamel.• At this age,calling attention to the harmful
habit is generally all that is necessary to stop the habit.
