Enhancing dental remineralization and antimicrobial properties with Ag nanoparticles-loaded mesoporous bioactive glass in reinforced dental resins: A one-pot synthesis approach

Abstract

Secondary caries develops between the dental filling and the tooth surface because the filling materials lack antibacterial properties. In our study, we successfully created Ag-mesoporous bioactive glass (MBG) with antibacterial properties using a one-pot synthesis method and modified its surface with bisphenol A-glycidyl methacrylate (Bis-GMA). We tested the antibacterial and remineralizing abilities of the resin matrix. The 10 wt% Bis-GMA-Ag-MBG composite resin showed excellent remineralizing and antibacterial abilities, and the presence of Ag nanoparticles did not affect these properties during the photocuring process. Cell viability experiments confirmed that the 10 wt% Bis-GMA-Ag-MBG composite resin is biocompatible. This study emphasizes the potential of Bis-GMA-Ag-MBG (10 wt%) as a new dental composite resin with bioactive, remineralizing, and antibacterial properties, addressing the critical need for durable and preventive dental materials against secondary caries.
