Low-level Laser Therapy in Enhancing Wound Healing and Preserving Tissue Thickness

Objective: The aim of this study was to determine the effects of Low Level Laser Therapy (LLLT) on wound healing at Free Gingival Graft donor sites (FGGDS). Materials and Methods: Forty patients requiring FGG were selected for this randomized controlled double blinded prospective clinical trial. The FGGDS were treated with LLLT and compared with an untreated control group. The Wound Healing Index (WHI), tissue consistency, colour match (CM), and H2O2 bubbling test for the evaluation of complete wound epithelialization (CWE) were recorded at the 3rd, 7th, 14th and 21st days. The pain-burning level, number of analgesics, and bleeding were recorded for 7 days. Donor area soft tissue thickness (TT) was measured at baseline and at the 1st month.
