Photobiomodulation (PBM) is widely being used to improve the wound healing process in dentistry and a vast majority of studies have proven its benefits. This review states that PBM can be helpful to improve secondary intention wound healing.

The goal of this systematic review and meta-analysis was to determine the effect of photobiomodulation (PBM) as an adjunctive treatment to periodontal therapies to evaluate secondary intention gingival wound healing and post-operative pain.

Five databases were searched and twelve studies were included that reported the result of the application of PBM on secondary gingival healing wounds and post-operative pain and discomfort after periodontal surgeries. Two independent reviewers selected the eligible studies and the outcomes of interest were extracted. The quality of eligible studies was assessed using the Cochrane Handbook for Systematic Reviews of Interventions.

--The application of PBM as an adjunct to periodontal surgeries resulted in a significant improvement in wound healing indices.

--The Landry wound healing index at the 7th postoperative day was significantly improved in PBM?+?surgery groups compared to the control groups.

--There was also a statistically significant increase in the complete wound epithelialization on the 14th postoperative day compared to the control groups.

--The methods used to assess the postoperative pain were heterogeneous, and therefore the results were limited which made the meta-analysis for postoperative pain assessment not possible.

Based on the results of this review, PBM can be effectively used as a method to improve secondary intention wound healing.
