Bactericidal efficacy of Er,Cr:YSGG laser irradiation against <i>Enterococcus faecalis</i> compared with NaOCl irrigation: an <i>ex vivo</i> pilot study

Abstract

In teeth with straight roots the Er,Cr:YSGG laser reduced the viable microbial population in root canals with small and large apical foramina but did not eradicate all bacteria. Three percent NaOCl inhibited the growth of E. faecalis and effectively sterilized all root canals.
