Preventive and therapeutic effects of semiconductor laser on pain in root canal treatment

Semiconductor laser can effectively reduce postoperative pain after root canal treatment and improve patient comfort. The combined application of laser-activated irrigation and low-level laser therapy techniques is the optimal pain prevention and control protocol, which can continuously provide analgesic effects for 14 days after treatment. As an adjunctive treatment, semiconductor laser effectively reduces discomfort in root canal treatment by enhancing root canal disinfection and promoting inflammatory tissue repair. This study provides scientific evidence for the rational application of semiconductor laser in clinical root canal treatment, which is of great significance for improving the success rate and patient satisfaction of root canal treatment.
