Abstract

The purpose of this study was to determine the bactericidal effect of a CO₂ laser used in a continuous mode. Classically prepared root canals were irradiated under standardized conditions with power settings of 2, 4, and 6 Watts. The mean elimination of Enterococcus faecalis in prepared and infected root canals of extracted teeth was 98.97%, 99.51% and 99.34% respectively. Minimum elimination was 91.67% and maximum 99.696%.
