Laser Applications in Endodontics

Since the development of the ruby laser by Maiman in 1960 and the application of the laser for endodontic field by Weichman in 1971, many papers on the applications of lasers have been reported. However , there are few review articles on laser applications in endodontics. The purpose of this study was to summarize the laser applications in endodontics. This paper includes diagnosis of dental pulp, treatment of dentinal hypersensitivity, applications for the treatment of pulp capping and pulpotomy, effects of laser on root canal walls, sterilization of root canals, root canal preparation by laser, effects of laser on periodontal tissues , application for apicoectomy, and other applications for endodontic treatment. The essential question is whether a laser can provide equal or improved treatment over conventional care. This article reviews the role of lasers in endodontics since the early 1970s, summarizes many research reports from the last decade, and proposes what the future may hold for lasers in endodontics. With the potential availability and future development of different laser wavelengths and methods of pulsing, much interest is developing in this promising field. (J. Jpn. Soc.
