Abstract

To evaluate the efficacy of photobiomodulation (PBM) on primary wound healing and patient-centered outcomes following esthetic clinical crown lengthening with osteotomy over a three-month follow-up period. Twenty-seven systemically healthy patients presenting 0.05). However, esthetic crown lengthening surgery resulted in significant improvements in patient satisfaction and oral health-related quality of life from baseline to three months of follow-up (p < 0.001). Photobiomodulation did not enhance primary wound healing or reduce postoperative pain following esthetic clinical crown lengthening with osteotomy. Nevertheless, the surgical procedure significantly improved patient satisfaction and quality of life over a three-month follow-up period.

How strong is the evidence?

Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
