The dental amalgams to mercury are the subject of a public consultation currently in Europe, led by the scientific Committee of the emergent and new sanitary risks (CSRSEN) of the European Commission.
In a report préliminaire1 put back in November 2007, the CSRSEN concluded that the dental amalgams, that are constituted mainly of mercury, don’t represent a risk for the patient’s health. Very few secondary effects have been observed and no illness can be associated to their presence in the mouth, underline the scientific committee.
The dental amalgams clear weak quantities of mercury steam, according to the CSRSEN, in general. The rates emitted by the amalgams. of 3. G to 17. g per day. are of many on this side of the doorsteps of toxicity. about 346. g per day.
The scientific committee also bent on the increasing use of the solutions spare to the alloys of mercury as the composites, the resins or the ceramics. They are also securities, one can read in the report.
These products are made of complex materials of which some could react with a caries or the gum, underline the CSRSEN however. Some among them could be toxic or could drag some mutations, raised in vitro studies. However, add the committee, these chemical materials are used since more of 30 years and very few undesirable effects are associated there.
The consultations will end February 22, 2008. The preliminary report could be reviewed then in order to take into account the set down opinions.
A topic of controversy
" The present scientific data show that the dental amalgams have again their places in dentistry. Although the absence of risk has not been demonstrated, the studies don’t permit to join the alloys of mercury to the supposed symptoms", affirm Benito Saucy, dentist and director of the services with the members to the Canadian dental association.
The academy of dentistry biocompatible of Quebec is, for his/her/its part, against the use of dental alloys to mercury. " To make itself/themselves an opinion, he/it misses a lot of studies again on the environmental consequences of the mercury use. Possibly, it is our health that will be touched", advance Pierre Larose, dentist and former secretary of the academy.
