Abstract
AIM: To evaluate the antimicrobial efficacy of different irrigants combined with silver nanoparticles. MATERIALS AND METHODS: Thirty-five patients were divided into seven groups (two control and five experimental), including Group 1: negative control (normal saline), Group 2: positive control (sodium hypochlorite), and Group 3 (sodium hypochlorite + AgNP), Group 4 (Twin Kleen), Group 5 (Twin Kleen + AgNP), Group 6 (Q Mix), and Group 7 (Q Mix + AgNP). Pre- and post-treatment bacterial samples were collected for analysis. RESULTS: Sodium hypochlorite combined with silver nanoparticles demonstrated the highest antimicrobial efficacy among the tested irrigants, with a significant difference confirmed by the Chi-square statistical analysis. CONCLUSION: Within the limitations of the study, it can be concluded that sodium hypochlorite when mixed with the silver nanoparticles showed higher antimicrobial efficacy as compared to the other tested groups.
