Current status of laser applications in endodontic treatment

The use of lasers in endodontic treatments has gained popularity owing to their safety and efficacy. Commonly utilized laser types in endodontic treatment include erbium, neodymium, water, carbon dioxide, and semiconductor lasers. In the future treatment of pulpal diseases, lasers may play a more significant role. A comprehensive review of the literature on the use of different lasers in endodontic treatment was conducted using Pubmed, Web of Science, Scopus, and ScienceDirect databases. The review included 97 studies that examined the principle, characteristic, and potential application in treating endodontic diseases of different lasers including Er:YAG lasers, water lasers, diode lasers, CO2 lasers, and Nd:YAG lasers. This review enhances our understanding of the current status as well as future application of lasers in endodontic treatment and aids in the development of new therapeutic approaches from a laser perspective.
