AMALGAM USE IN CBC HEALTH SERVICES
• CBCHS was the first institution in Cameroon to make the pioneering decision to stop amalgam use.
• It started mercury-free dentistry in 2005 at Etoug-Ebe Baptist Hospital in Yaoundé.
• In 2007, the decision was fully implemented in all dental clinics throughout the CBCHS.

AMALGAM USE IN CBC HEALTH SERVICES
• Dental Amalgam an alloy containing mercury.
• one of the most commonly used materials
restorative dentistry over the years.
• Learnt about the toxicity of Amalgam while
in school some two decades ago.
• Had worked with amalgam for more than
a decade.

AMALGAM USE IN CBC HEALTH SERVICES
• PROCEDURE:
• Started with the measuring of powder with a spoon and dropping mercury from a pipette
• Then advanced to using capsules but dropping mercury.
• Later on went to encapsulated powder and mercury.

MANAGEMENT OF EXCESS MERCURY :
• The mixed amalgam was put in a tissue
• Excess mercury was sequenced in a trash
cans

• Later on in bottles containing water that was
emptied in the toilets
• Mercury balls were spread on the floor
which often broke down into smaller balls and
difficult and dangerous for the house keepers to take care .
Aspirators were used in the mouth

• We understood that amalgam waste management was not the best.
• This therefore called for more reading on it
• The fact that amalgam was very dangerous to dental personnel and equally that a patient with amalgam even after death still has the potential to contaminate the environment caught our extension very much.
• In 2005, we then started phasing down amalgam in our institution.
• Final phase out in 2007

HOW?
• Stopped the purchase
• Reduced use bit by bit
• Encouraged staff on use of alternatives as composites and glass ionomeres.

SOME DIFFICULTIES ENCOUNTERED• Change as usual was difficult for many staff needing education
• Failed fillings for lack of experience in using alternatives
• Retraction of some fillings
• Some clients were used to hard filings as amalgam needing education
• The cost could have been a problem but as a Faith based institution, all were done at the same price with the amalgam.

SUCCESS STORY
• FROM 2008, NO AMALGAM USE IN ETOUG-EBE BAPTIST HOSPITAL

IMPACT
• Improved oral health of patients

![Page 16: EXPERIENCE ON PHASE OUT ALMALGAM IN CBC HEALTH … · •Dental Amalgam an alloy containing mercury. •one of the most commonly used materials restorative dentistry over the years](https://reader034.vdocuments.net/reader034/viewer/2022050402/5f800f7c39630a0d2d20dc71/html5/thumbnails/16.jpg)
STRATEGIES TO ENCOURAGE PHASE DOWN AMLGAM IN CAMEROON
• Work with the Dental Order on sensitization of Dental Practitioners on the
toxicity of mercury in amalgam to humanity and environment with the
necessity to phase it down,
• Sensitization of the community of Cameroon through media, social groups ,
schools, etc.

STRATEGIES TO ENCOURAGE PHASE DOWN AMLGAM IN CAMEROON
• Work with Dental Suppliers on alternatives to amalgam,
• Work together with dental Faculties on their curricula focusing more on the
alternatives.
• Encourage the use of separators and encapsulated amalgam for those still having
amalgam in their clinics or when removing old amalgam filling.
• Encourage phase down/phase out regulation by the Ministry of Public Health with
end of amalgam use for pregnant women and milky teeth in 2020; and total phase
out for all in 2025.
