Bisphenol A in contemporary dentistry: from material chemistry and exposure pathways to potential clinical relevance-a comprehensive narrative review

Introduction

Resin-based dental materials have substantially improved contemporary dental care while raising interest in their long-term biological safety. Attention has focused on bisphenol A (BPA), which may be associated with dental materials through BPA-derived monomers, residual impurities, or degradation processes. This narrative review critically synthesizes current evidence regarding BPA in dentistry, focusing on its origin and availability, biological implications, clinical relevance, and regulatory perspectives.
