Senate Bill No. 2990
Mercury in Dental Fillings Prohibition Act
filed by Senator Miriam Defensor-Santiago
An Act Prohibiting the Use of Mercury in Dental Fillings
FIFTEENTH CONGRESS OF THE REPUBLIC
OF THE PHILIPPINES
Second Regular Session
Introduced by Senator Miriam Defensor Santiago
Elemental mercury and mercury compounds are known to be toxic and hazardous to human health and to the environment. Despite its toxicity, however, mercury continues to be used in the Philippines as a component in dental fillings.
A dental amalgam, commonly referred to as a “silver filling,” consists of 42 to 58 percent mercury, and contains 112 to 3/4 of a gram of mercury. Consumers may be deceived by the use of the term “silver” to describe a dental amalgam, which contains substantially more mercury than silver.
The mercury contained in dental amalgam is continually emitted in the form of mercury vapor, and the total amount of mercury released depends upon the total number of fillings; their age, composition, and surface area; the intra-oral presence of other metals; dietary and lifestyle habits; and other chemical and metabolic conditions affecting the mouth. When mercury vapors are inhaled, most of the mercury (about 80 percent) enters the bloodstream directly through the lungs and then rapidly deposits preferentially in the brain and kidneys. Mercury is scientifically known to cause birth defects or other reproductive harm. The mercury from amalgan1 passes through the placenta of pregnant women and through the breast milk of lactating women, increasing health risks to both unborn children and newborn babies.
According to the World Health Organization, the estimated average daily intake and retention of mercury from dental anmlgam ranges from three to 27 micrograms per day, and is greater than all other sources combined.
Further, mercury from dental an1algam can enter the environment during any point of the product’s life-cycle. This includes placement or removal of fillings; through bodily excretions; when sewage sludge is incinerated, spread on crops, or dumped in landfills; when vapor is released or land-filled; when vapor is released directly from the filling (which increases with brushing, chewing, and consuming hot foods or salt); and during cremation.
When discharged to the environment, conditions may be right for waste dental mercury to methylate, become bioavailable, and subsequently biomagnify in fish as methyl mercury, the
most toxic form of mercury.
Highly effective and durable alternatives to mercury-based dental fillings exist, and must be made available to consumers and included in publicly and privately financed health plans.
Consumers and parents have a right to know, in advance, the risks of placing a product containing a substantial amonnt of mercury in their mouths or the mouths of their children.

Mini LED Autofocus claims to be the first to automate the clinical process of polymerization. The active system constantly calculates the ideal power density for indepth curing of composite resin. It is made possible by a complex telemetry system and an innovative microprocessor.
It is said to be the most powerful LED light on the market with an output of more than 2 200 mW/cm2. Its high light intensity and 100% light spectrum enables rapid curing of dental composites without heat generation.
In the Philippines, Mini LED Autofocus can be bought at Acteon Philippines. Its address is 4th Floor ALCO Building, 391 Senator Gil Puyat Ave., Bel-air, Makati. Telephone numbers 02 89978 66 to 67.
