The efficiency of high powered diode laser in root canal disinfection – a case report

Abstract

The aim of this case report is to describe a mandibular second molar with periapical lesion and rare anatomy of the endodontic system which was treated with additional method of root canal disinfection. Intra oral radiograph revealed a tooth with not exacting endodontic treatment and with relatively large apical radiolucency. The additional disinfection performed after the root canal preparation was finished with diode laser for 20 sec. The 18-month follow-up revealed complete resolution of the periapical radiolucency.
