BPA/Bisphenol a in Dental Materials

Abstract

Objective: Through search, the literature and understanding the release of bisphenol-A (BPA) during treatment with the dental material, Further, would like to discuss whether it is possible to manage it to a greater extent to promote patient safety. Methodology: By searching information in PubMed, Google scholar, and the library of Universidad Europea de Madrid, with a limit placed over the last 10 years, in English, and Spanish. Keywords: bisphenol a, dentistry, dental restoration materials, orthodontics, endodontics and patient safety. Results: A total of 16 studies were using. In saliva, the BPA release is increased the initial 5 min to I hour, with dental material placement show in most studies. Then BPA decreases after 24 hours of dental material placement. In urine, BPA release was detected 24 hours after placement. Ultimately, after 30 days, BPA will return to the level prior to placement of the dental material. In Blood before and after treatment in adults, no BPA has been detected in the blood serum. Conclusion: 1. According to these studies, Bisphenol-A will release: After dental material (orthodontic adhesive; composite resin; endodontic cement) placement in 30 min. Greater light-curing tip distances. Show up of the oxygen inhibited layer of composite. The number of the composite surface to be placed is positively correlated with BPA release. 2. Ａs dentists, protect patients' safety as far as possible without affecting dental treatment. Certain measures can be taken to reduce the release of BPA in the clinical setting, for example, use of rubber dams, immediate polishing of all resins used to avoid uncured layer formulation and rinsing of the mouth after handling. Also, a preventive measure is to use a minimum number of restorers or sealants in each appointment.
