Anti-biofilm efficacy of nano calcium hydroxide and chitosan nanoparticles againstE. faecalis.

Enterococcus faecalis is among the microorganisms frequently isolated from root canal infections. The outcome of the endodontic treatment depends on the effective disinfection of the root canal system. Therefore, it is of interest to assess the potential of Nano Calcium Hydroxide and Chitosan Nanoparticles as intracanal medicaments against Enterococcus faecalis biofilm. Hence, a total of twenty-eight single-rooted dental elements were included, where the incisal end of individual elements was infected with Enterococcus faecalis. The two medicaments used as intracanal dressing materials were Nano Calcium Hydroxide and Chitosan Nanoparticles. Enterococcus faecalis bacteria exposed to Nano Calcium Hydroxide was significantly higher as compared to those exposed to Chitosan Nanoparticles.
