- Abstract
Objective To study the antibacterial effect of polymethyl methyacrylate (PMMA) resin base containing Ag-TiO2 antibacterial agent against common conditioned pathogen and their bacterial plaque in vitro. Methods Different qualities of Ag-Ti02 antibacterial agent were added into PMMA resin base in order to prepare antibacterial PMMA resin base. Then, in vitro analysis of antibacterial effect of the resin base against Streptococcus mutans, Staphylococcus aureus, Saccharomyces albicans were assayed with the pellicle-sticking method. Furthermore, the growth of Streptococcus mutans and Saccharomyces albicans bacterial plaque on the antibacterial PMMA resin base were examined by scanning electron microscope. Results The inhibition percent for Staphylococcus aureus was 93.3% by antibacterial PMMA resin base with 0.7% Ag-Ti02; for Streptococcus mutans 90.2% with 1.5% Ag-Ti02; for Saccharomyces albicreaensnhisna 91.2% with 2.5% Ag -TiO2.Bactrial plaque of Streptococcus mutans and Streptococcus mutans and Saccharomyces albicans antibacterial resin base were inhibited effectively. Conclusion The antibacterial property of the PMMA rasin base is effectively enhanced with Ag-Tio2 antibacterial agent.
