Exposure to bisphenol a in dentistry – Current Views
Journal Title: INTERNATIONAL JOURNAL OF CURRENT RESEARCH - Year 2015, Vol 7, Issue 4
Abstract
Bisphenol a is xenoestrogen synthesized in large quantities worldwide for production of polymers (polycarbonates, epoxy resins) and thermal paper. This determines its universal presence - in everyday products (packaging, containers and bottles), food and drinking water. Food is considered to be the most important source of population exposure; however, in overall exposure assessment consumption of drinking water, inhalation of dust and dermal contact with thermal paper must be taken into account. Exposure to BPA and its derivatives from dental composites and sealants is possible. High levels of BPA in saliva (especially immediately or one hour after dental treatment), decreasing over time have been found. No BPA in the blood samples of dental patients have been detected, as reported in the available studies. High urinary levels of BPA after treatment with dental composites and sealants have been reported. The degree of exposure to BPA from dental materials and the possible adverse health effects are insufficiently investigated. No data were found in the available literature concerning the urinary levels of BPA among occupationally exposed dental professionals, in comparison with those among dental patients after treatment with composites and sealants.
