ABSTRACT
Elastomeric impression materials were widely utilised because they reproduce details accurately, but they also carry a lot of infectious organisms from the oral cavity. Conventional spray and immersion methods were used previously which leads to dimensional changes. So, this study aimed to evaluate the antimicrobial activity of polyether impression material incorporated with various concentrations of copper oxide nanoparticles. A total of 60 medium-body polyether impression material samples were made and divided into 2 groups based on organisms with 30 in each. The 30 specimens in each group were further divided into 5 subgroups based on the concentration of copper oxide nanoparticles. The antimicrobial activity against S. mutans and C. albicans was assessed using the Kirby-Bauer disk diffusion method. The obtained data were subjected to statistical analysis. Analysis of variance and post-hoc tests were used to identify the significant differences within and across the groups, respectively
