Antimicrobial Activity of Root Canal Sealers on Facultative Gram-positive Cocci

Abstract

Objective: Antibacterial effect of several root canal sealers were compared which have different chemical structures. Materials And Methods: Enterococcus faecalis (EF) incubated into brain-heart infusion agar at 37 C for 24 h. 20 mg of used root canal sealers were impregnated blank antimicrobial discs which were Endomethasone N, AH Plus, MTA Fillapex and Sealapex. Each plates were separated four quadrants and root canal sealers impregnated antimicrobial discs were inserted into their quadrants. Inhibition zones were measured with eye-witness on the plates by well-educated specialist after 48 h. Results: Endomethasone N have made higher inhibiton zones than other root canal sealers. AH Plus has larger inhibition zone than MTA Fillapex and Sealapex. Sealapex has less antibacterial effect on E. Faecalis. Conclusion: The results demostrated that eugenol based root canal sealers have significant antibacterial effects.
