In a study published in the October edition of the Journal of the American Dental Association they claim that an increased intake of the mineral from drinking water, dentifrice, infant powder products or bev- erages can lead to a higher risk of developing fluorosis, a condi- tionthatdiscoloursandweakens teeth. The findings confirm earlier evidence indicating a link be- tween dental fluorosis and greater intake of fluoride in early life. The latest study, conducted by researchers from the Univer- sity of Iowa in the United States, found that a greater fluoride in- take from reconstituted powder, apopularchoiceforinfantfoodin the US, and other beverages with added water increased fluorosis risk in children between the ages of three and nine months. They suggested avoiding the ingestion of additional fluoride through consumption of these mixtures inordertoreducetheprevalence of the condition nationwide. According to the US Centers for Disease Control and Preven- tion, one-third of children be- tween the ages of 12 to 15 years in the US suffer from some form of fluorosis. The country also has the highest occurrence of flouri- dated water in the world.

In a review published in the latest Journal of Alzheimer’s Disease, researchers associated withuniversitiesinBoston(USA), Freiburg/Breisgau and Frankfurt (Oder), both in Germany, claim that symptoms of the condition were reproduced or accelerated when brain tissue was exposed to inorganic mercury, the main ingredient of amalgam. Earlier studies of low-dose human exposure, such as to den- tists and their staff, have shown that exposure to mercury is cor- related with long-term neuro- logical or psychological harm. The new review is one of the first that has found a systematic link between memory deficits and ncreasedlevelsofmercuryfound in Alzheimer’s patients. According to Prof. Harald Wa- lach, Viadrina European Univer- sity in Frankfurt (Oder), patients with silver fillings are exposed to 1 to 22 µg mercury per day, of which the majority accumulates in the brain. The metal binds with selenium, a substance respon- sible for preventing oxidative stress,whichcanleadtocelldeath and early ageing. Removing mer- cury from medical and ecological cycles could slow down cell death and prevent the development of dementia and possibly other forms of neurological disorders, including Parkinson, he added. “Thesituationissimilartothe early 1970s regarding smoking: substantialexperimentalevidence existed, but human studies were inconclusive at the time and wereunderattackbygroupswith a vested interest,” Prof. Walach told Dental Tribune Asia Pacific. “To wait until irrefutable evi- dence has accumulated is not the best option in view of what we already know about the toxic potential of mercury.” Amalgam is still the most common type of filling used by dentists worldwide. It is banned in Sweden and restricted in Nor- way and Denmark. (Edited by Daniel Zimmermann, DTI) DT New evidence links mercury to Alzheimer’s
