On-Site Speaker (Planned) Santiago Orrego
Abstract Scope Oral bacteria form biofilms on hard tooth surfaces and dental materials which posses threat on the structure's integrity. Current solutions to prevent biofilm formation are using bioactive resin-based dental materials incorporating anti-bacterial agents such as nanoparticles of silver (NAg), quaternary ammonium dimethacrylate (QADM), and nanoparticles of amorphous calcium phosphate (NACP). In this study, we propose a novel approach to repel the formation of biofilm by incorporating piezoelectric nanoparticles in a resin-composite dental material system. The oral biofilm viability was monitored by the live-dead assay to reveal the repelling action and mechanical evaluation was carried out. Results indicate that the piezoelectric nanoparticles prevented the formation of the biofilm without affecting the mechanical properties of the resin-composite system. The novel method of combining piezoelectric agents may have wide applicability to other adhesives for caries inhibition.
