Antibacterial Effect of Polymethyl Methacrylate Resin Base Containing TiO2 Nanoparticles

Restorations in dentistry must reproduce the aspect of patient’s natural teeth and require non-toxicity, biocompatibility, good mechanical properties order to last longer. are permanently contact with microbes that can adhere form biofilms. The purpose this study was determine adhesion extent Streptococcus mutans polymethyl methacrylate (PMMA) resin base containing TiO2 nanoparticles. To understand on modified resin-based surfaces, following surface were measured: roughness, angle, zeta potential CIE color parameters. Evaluation tensile stress performance PMMA showed maximum decreases an increasing amount roughness causes angles border between hydrophilic hydrophobic surfaces. All studied surfaces negatively charged added tends increase potential. addition nanoparticles increases lightness intensity red yellow color. into morphological change bacterial cells.
