Abstract
The main aim of the study was to find the antimicrobial properties of a poly methyl methacrylate resin (PMMA) which is modified with silver-doped titanium dioxide nanoparticles. This research study was done to prove that the incorporation of silver-doped TiO2 nanoparticles improves the antimicrobial and antifungal properties.The poly methyl methacrylate resin (PMMA) powder was modified using 0 wt%(control) 1wt% and 3wt% silver doped TiO2 nanoparticles Test specimens were prepared of dimensions 5 mm × 5 mm × 2 mm. The antimicrobial properties of the specimens were evaluated by calculating CFU/ml. The obtained values were analyzed by one-way analysis of variance (ANOVA), Kruskal Wallis test, and post-hoc Tukey’s test at a significance level of 5%. The incorporation of silver-doped titanium dioxide nanoparticles into denture base resin improved antimicrobial activity. Compared to 1% and 3% nanoparticle doped, 3% has given better antimicrobial activity calculated using CFU/ml. It is reduced to one-fourth the microbial growth compared to the control group. The addition of silver-doped titanium dioxide nanoparticles to denture base resin is an effective method for antimicrobial and antifungal action.
