Bactericidal effect of Nd:YAG laser irradiation on some endodontic pathogens <i>ex vivo</i>

Abstract

The Nd:YAG laser irradiation is not an alternative but a possible supplement to existing protocols for canal disinfection as the properties of laser light may allow a bactericidal effect beyond 1 mm of dentine. Endodontic pathogens that grow as biofilms, however, are difficult to eradicate even upon direct laser exposure.
