Background: Recently, there has been increased interest in the in vivo release of dental sealant components, such as bisphenol A (BPA), which has the potential to bind the estrogen receptors of relevant cells at subtoxic concentrations in vitro, impairing the development, health and reproductive systems of wildlife. The purpose of this systematic review was to investigate whether the placement of pit and fissure sealant materials causes toxicity, and thus harms patients.
Methods: The literature search (from the earliest record up to March 2007) for relevant articles was done with Ovid MEDLINE, CINAHL and other bibliographic databases.
Results: A total of 377 articles were identified by the literature search; relevance was determined by examining the title and abstract of the articles. Eleven original studies met the inclusion criteria. These articles were read in full and scored independently by 2 reviewers.
Recommendations: The evidence suggests that patients are not at risk for exposure to BPA from the use of dental sealants. To reduce the potential, if any, for BPA toxicity from sealants, dental providers should use a mild abrasive, such as pumice, either on a cotton applicator or in a prophy cup; have older children and adolescents gargle with tepid water for 30 seconds; or wash the sealant surface for 30 seconds with an air-water syringe while suctioning fluids and debris from a child's mouth.
