Which dental materials commonly contain Bisphenol A (BPA)?

The presence of Bisphenol A (BPA) is particularly noteworthy in dental composites and sealants. These materials are constructed from resins that can metabolize into BPA, especially during processes such as polymerization. Composites, which are frequently used for restorative procedures due to their aesthetic qualities and strength, often incorporate bisphenol-based resins. Sealants, applied to prevent decay in the occlusal pits and fissures of teeth, also can contain components derived from BPA.

Recognizing that composites and sealants may release small amounts of BPA over time, there has been a movement toward developing BPA-free alternatives to prioritize patient safety while still ensuring that dental materials perform effectively. This aligns with the current trend in dental materials research, which seeks to reduce or eliminate potentially harmful substances without sacrificing performance.

Other materials like cements and adhesives can contain various components, but their BPA content is typically less of a concern compared to composites and sealants. Amalgams and glass ionomer cements (GICs) do not normally use BPA-based components, focusing instead on metals and silicate glass respectively. Surgical materials, while critical in dental procedures, are generally unrelated to BPA discussions in the context of dental restorations.
