New Insight Into Laser Applications in Endodontic Dentistry: A Comprehensive Review

There is limited clinical information regarding the efficacy and safety of laser treatment in endodontics and dentistry. This comprehensive literature review discusses the clinical efficacy, advantages and limitations of laser use in these fields. Carbon dioxide (CO₂), diode, erbium-doped yttrium aluminium garnet (Er: YAG), Er, Chromium (Cr): YAG, and neodymium (Nd): YAG lasers have been used in endodontic treatments. Laser technology has revolutionised endodontic treatment by enhancing disinfection, promoting healing, facilitating root canal treatment, improving canal shaping and decreasing pain associated with endodontic treatments. General dental care has improved by laser advancements in drilling, preparing cavities, reshaping the gingiva, teeth bleaching, addressing periodontal disease and diagnosis. Their high precision results in minimal disruption of adjacent tissues, which in turn minimises bleeding, decreases patient discomfort, and accelerates recovery times. Further clinical randomised studies are required to compare laser treatments with conventional methods, particularly in the context of cost-effectiveness.
