Products were analyzed for mercury content and other relationships. In all of the fifteen products surveyed, mercury analysis was undertaken. None (0%) of the products tested were found to contain even trace amounts of mercury. The majority of the products were imported, coming from either the Ivory Coast or France (Tab. B.2). None (0%) of the products offered a statement to indicate mercury content. Prices ranged from 0.15 XOF to 33.33 XOF per gram of product. Of those products, the French imports demanded the highest prices, from five to ten times more than those coming from other African countries. The one USA import also carried a high price tag. Active ingredients did not show any relationship to price. Labels for products offered were well-defined and included more than just active ingredients and listed most product ingredients. One active ingredient listed frequently in products in Senegal is hydroquinone. Many of the products offered strictly cosmetic solutions related to sunscreens and were prevalent in many higher-priced offerings. 3.2.5 Status of availability and use of dental amalgam and mercury-free alternatives for dental restorations in Dakar and Thies, Senegal Participants. The Dental Survey was done with fourteen (14) dentistries. The survey was done in two types of dentistries: eight (8) public dentistries (which belong to Senegalese state) and six (6) private dentistries. Alternative restorative materials have been widely adopted in dental practices. None of the dentists used only amalgam as a restorative material (0%); most used both amalgam and non-mercury materials; and some dentists used only non-mercury materials. For dental materials, public dental offices offer a lower-cost service while private dentists cater to the more affluent. According to public health dentists, all people can afford a non-mercury tooth restoration at public dentistries. But, according to most private dentistries, only those earning an average income or better can afford a nonamalgam filling at a private dentistry. 30

Some of the patients requested mercury-free fillings. All of the dentistries stated that some (likely 5 – 20%) of their patients ask for mercury-free fillings. A wide variety of alternative materials and prices were offered at dental offices. Of the dentists interviewed, five (5) used composite materials only; four (4) used composite and silver fillings (made up of silver and zinc); five (5) used composite and glass ionomer as an alternative filling material. The main alternative filling type/filling material used by dentists who use both, mercury-containing and mercury-free fillings is composite. Prices to patients for either material were somewhat comparable, but alternatives cost more. The price difference for patients at public dentistries goes between 5,000 XOF to 20,000 XOF for mercury-free alternatives and 3,000 XOF to 10,000 XOF for mercury amalgam. This range overlap fails to indicate that in all offices, amalgam was less expensive than a mercury-free alternative. The price difference for patients at private dentistries goes from 12,500 XOF to 60,000 XOF for non-mercury restorations; and from 3,000 XOF to 10,000 XOF for mercury amalgam. Training for placing alternatives is widespread and has not affected prices, while equipment costs have. According to all interviewed dentists, the methodology for mercury amalgam or alternatives (composite, CVI or silver fillings) is similar and both are taught in dental school. So, no additional training costs are necessary. But equipment purchases for placing alternative fillings were estimated to run about 656,000 XOF 5 (lights e.g. for photo curing etc.). Dentists indicated material costs differed significantly requiring them charge more for alternatives. In addition to equipment costs, the materials costs for alternatives are responsible for the price differential between the amalgam/alternative materials. Dental offices understood the risks posed from mercury. None of the dentists interviewed used only amalgam. All dentists (100%) were aware of the risks posed by mercury to human health and the environment, believe references to mercury’s dangers are not overstated, and have heard about mercury’s health risks. 5 Cost for equipment estimated as 1,000 EUR, conversion from EUR to XOF is fixed at 655.957 XOF = 1 Euro 31
