Mercury derived from dental amalgams and neuropsychologic function.
There is widespread concern regarding the safety of silver-mercury amalgam dental restorations, yet little evidence to support their harm or safety. We examined whether mercury dental amalgams are adversely associated with cognitive functioning in a cross-sectional sample of healthy working adults. We studied 550 adults, 30-49 years of age, who were not occupationally exposed to mercury. Partic...
متن کاملA prospective study of prenatal mercury exposure from maternal dental amalgams and autism severity.
Dental amalgams containing 50% mercury (Hg) have been used in dentistry for the last 150 years, and Hg exposure during key developmental periods was associated with autism spectrum disorders (ASDs). This study examined increased Hg exposure from maternal dental amalgams during pregnancy among 100 qualifying participants born between 1990-1999 and diagnosed with DSM-IV autism (severe) or ASD (mi...
متن کاملTheoretical Models of Mercury Dissolution from Dental Amalgams in Neutral and Acidic Flows
This article reports an experimental and theoretical investigation of mercury dissolution from dental amalgams immersed in neutral (noncorrosive) and acidic (corrosive) flows. Atomic absorption spectrophotometric measurements of Hg loss indicate that in neutral flow, surface oxide films formed in air prior to immersion persist and effectively suppress significant mercury release. In acidic (pH ...
متن کاملReport on Mercury Toxicity from Dental Amalgams and Thimerosal Presented to Congressional Hearing
In developing an opinion on mercury toxicity from exposures to dental amalgam and thimerosal I have reviewed toxicologic data relevant to animal and human studies to environmental mercury, methylmercury, thimerosal and exposure to mercury from amalgam fillings. I have reviewed literature searches conducted on various computerized databases; evaluated published literature on primary studies as r...
متن کاملMercury evaporation from amalgams with varied mercury contents.
This study examined the relationship between mercury content and mercury evaporation from amalgams during setting. Two different types of commercial high-copper amalgams (single composition and admixed types) were used. Cylindrical specimens of each amalgam were prepared with five different mercury contents according to ADA Specification No.1. Specimens were also prepared by hand condensation. ...
