Abstract

Postoperative pain, inflammation and delayed healing continue to be significant concerns following periodontal surgical procedures. Therefore, it is of interest to compare the effects of light emitting diode therapy and low-level laser therapy on post periodontal surgical healing. Hence, a total of 100 patients undergoing periodontal flap surgery were randomly allocated to receive either LED therapy or low-level laser therapy and healing outcomes were clinically evaluated. Both therapies significantly enhanced postoperative healing, with low-level laser therapy demonstrating superior early pain control and faster inflammatory resolution. This study advances existing knowledge by offering direct comparative evidence on photobiomodulation modalities for optimizing periodontal surgical healing.
