Bisphenol A in Dentistry

Abstract

Bisphenol-A, an organic synthetic compound, has been present in many consumer plastic products and food packaging since the 1960s. Nowadays, Bisphenol-A is widely used in the field of dentistry for the manufacturing of resin materials. Several studies have suggested that Bisphenol-A may cause adverse health effects due to its ability to act as an endocrine disruptor chemical which has raised concerns about its widespread use. The aim of this study is to present an overview of the research studies dealing with Bisphenol-A exposure in the field of dentistry. PubMed, Scopus, EMBASE, Europe PMC, Web of Science and reference lists of relevant papers were searched to identify articles for inclusion. Two authors screened literature and extracted data from included studies independently. The evidence supports that Bisphenol A is used in many fields of routine clinical dental practice such as restorative dentistry and orthodontics. Regarding Bisphenol-A exposure from dental materials, the current data concludes that is below the Tolerable Daily Intake levels, but further evaluation is needed to reveal any possible adverse events caused by low-dose BPA exposure.
