AIM: The aim of the study is to evaluate the effect of antibacterial efficacy and root dentin microhardness of Triple Antibiotic paste modified with Nano Zinc oxide and Nano Titanium dioxide.The Intracanal medicaments used were Triple Antibiotic Paste modified with Nano Zinc oxide and Nano Titanium dioxide. The antibacterial efficacy was evaluated using Colony Forming Unit analysis and microhardness at middle and apical third after 1 week were measured using Vickers Microhardness Tester. RESULTS: Within the limitations of this study, TAP with Nano Zinc oxide showed highest antibacterial efficacy and TAP with Nano Titanium dioxide showed least reduction in root dentin microhardness.

Keywords : Triple Antibiotic Paste, antibacterial efficacy, nanoparticle, intra-canal, medicaments, root dentin, micro- hardness.
