ABSTRACT

resin is becoming the major concern for many dentists worldwide. This study was carried out in order to compare and evaluate S. mutans biofilm adherence on surface of composite resin subjected to Sof-Lex polishing and contouring system and Shofu polishing system and mouthwashes like 0.2% CHX and 7.5% povidone iodine solution (PVI). Materials and methods: Samples (n = 30) of nanohybrid composite resin were randomly divided into three groups for polishing with aluminium oxide disks, Shofu composite polishing systems and mylar strip group followed by biofilm adhesion of S. mutans on those polished discs. These discs were then randomly treated with the mouthwashes to check for their efficacy against S. Mutans. Results: Smoother surface was generated with Sof-Lex aluminum oxide disks when compared to Shofu polishing systems. There was a statistically significant difference before and after immersion in CHX and PVI (p<0.01). The comparison of all the groups showed the largest decrease in PVI, followed by CHX. https://doi.org/10.5281/zenodo.6307338
