Comparison of Antimicrobial Efficacy of 0.2% Chitosan, 3% Sodium Hypochlorite, 2% Chlorhexidine against Enterococcus faecalis, Alone and in Combination with Diode Laser an In Vitro Study
Author(s): Pallavi Goel*
The aim of this study was to compare the antimicrobial efficacy of 0.2% chitosan, 3% sodium hypochlorite, 2%
chlorhexidine against Enterococcus faecalis, alone and in combination with diode laser.
The root canals of 72 extracted intact human single rooted teeth with single canals were prepared and E. faecalis was
incubated in the root canals for 7 days. The teeth were then randomly divided into the following 4 experimental
groups: Group I: Saline, group II: 0.2% Chitosan, group III: 3% Sodium hypochlorite and group IV: 2%
Chlorhexidine. These groups were further subdivided into 3 groups: a) 10 ml irrigant only, b) 10 ml irrigant, dried
and irradiation with diode laser, c) diode laser was used for activation of irrigant solution. Samples were obtained
from subgroups in each group and checked for turbidity. The effect of each irrigant was eval.. View more»
