ANTI MICROBIAL ACTIVITY OF ROOT CANAL SEALER- ANTIBIOTIC COMBINATION ON ENTEROCOCCUS FEACALIS – IN- VITRO STUDYAbstract
Aim and objective: The aim of the in-vitro study is to evaluate the Antimicrobial activity of root canal sealant- antibiotic combination on Enterococcus feacalis. Background: Elimination of microorganisms from the root canal system is the one of the most important objectives of RCT. Enterococcus faecalis (EF) has been the most frequently identified species in canals of root-filled teeth with periapical lesions. EF is extremely resistant to current treatment modalities in endodontics. Therefore, the success rate of root canal treatment can be significantly reduced with the presence of this microorganism at the time of obturation. So the root canal sealant along with antibiotic combinations are used to inhibit and kill the bacteria present in the surface walls of the canals. Methodology: The antimicrobial activity of root canal sealer- antibiotic combination on Enterococcus faecalis was tested agar well diffusion method. Results: Both the sealers tested in combination with clindamycin and amoxicillin showed greater zone of inhibition when compared with sealer with single antibiotic combination.
