Abstract

In the article, “Effect of Photobiomodulation on Transforming Growth Factor-β ₁, Platelet-Derived Growth Factor-BB, and Interleukin-8 Release in Palatal Wounds After Free Gingival Graft Harvesting: A Randomized Clinical Study,” by I. Keskiner et al., published in Photomedicine and Laser Surgery 2016;34:263–271, some of the data in Table 3 for PDGF-BB was included by mistake. The revised version of Table 3 with correct values is shown below.
