Effectiveness of calcium hydroxide plus points and chlorhexidine activ points against Enterococcus faecalis by agar diffusion test: An in-vitro study

Aims/Objectives: The aim of this study was to evaluate the antimicrobial effectiveness of two intracanal medicaments and their combination against Enterococcus faecalis, which are commonly found in root canals. Materials and Methods: In this study, the antimicrobial effect of chlorhexidine activ points, calcium hydroxide plus points and combination of both points after 1 st day, 2 nd day, 3 rd day, 7 th day, and 14 th day were evaluated using agar diffusion test. Anti-bacterial activity as evidenced by inhibitory zones of clearance around the medicament was observed and diameters (in mm) measured. Results: Chlorhexidine activ points show the maximum inhibition against E. faecalis calcium hydroxide points alone and when combined with chlorhexidine shows the minimal antibacterial efficacy. Conclusion: Chlorhexidine activ points obtained the highest antimicrobial activity compared with other medicament and can be the medicament of choice.
