Saudi Endodontic Journal, 12(3), 253-260. doi:10.4103/sej.sej_179_21https://doi.org/10.4103/sej.sej_179_21https://hdl.handle.net/20.500.12713/3298Since the laser was first used in endodontics in the 1970s, many studies have been conducted on this subject. This paper aims to summarize the studies about the effects of lasers in endodontics, which analyze the preparation and disinfection of the root canal system, postoperative pain, and the effect on the smear layer. The still-controversial question is; if lasers provide better results when used in tandem with conventional methods or alone. Another unknown factor is the side effects on teeth and surrounding tissues. With the increase in technology and knowledge in this field, developments are promising with different devices, laser tips, and wavelengths.eninfo:eu-repo/semantics/closedAccessEndodonticsIrrigationLaserPostoperative PainSmear LayerArticle1232532602-s2.0-8513836803010.4103/sej.sej_179_21N/A
