Methacrylate-based restorative resin (RBC)

Methacrylate-based restorative resins are synthetic biomaterials used extensively in clinical dentistry to restore the function and aesthetics of teeth damaged by caries or trauma (Ferracane, 2011) [1]. These materials are typically composed of a blend of dimethacrylate monomers, such as Bis-GMA or UDMA, which undergo free-radical polymerization to form a rigid, cross-linked polymer matrix (Goldberg, 2008) [2]. While they are not therapeutic targets in the traditional pharmacological sense, such as receptors or enzymes, they interact significantly with the oral environment and underlying biological tissues. Concerns regarding these materials often center on the release of unreacted monomers and degradation products, which can penetrate the dentin and elicit inflammatory or cytotoxic effects in the dental pulp (Schmalz & Galler, 2011) [3]. Furthermore, the presence of Bisphenol A (BPA) derivatives in some formulations has raised questions regarding potential endocrine-disrupting effects (Fleisch et al., 2010) [4]. The clinical success of these resins depends on their degree of conversion and the stability of the bond between the resin and the tooth structure. Research continues to focus on developing resins that can release therapeutic ions like fluoride to prevent secondary decay. Overall, they represent a critical interface between material science and oral biology.
