Physical/mechanical and antibacterial properties of composite resin modified with selenium nanoparticles.

Background: Accumulation of biofilm over composite resin restorations is one of the principal causes of recurrent caries. Therefore, this study aimed to develop antibacterial composite resins by crystalline selenium nanoparticles (SeNPs), assessing the antibacterial, mechanical, and physical properties of the composite resin after SeNPs incorporation.

Methods: SeNPs were synthesized via a green method.
