Antimicrobial action of photodynamic therapy in root canals using LED curing light, curcumin and carbopol gel

Abstract

Similar disinfection effectiveness was obtained using curcumin + LED curing light and methylene blue + 660 nm LASER (standard PDT). The use of carbopol gel did not favour a greater transmission of LED light along the root canal and also resulted in less bacterial killing when used in endodontic PDT.
