Efeito da fotomobiomodulação em duplo comprimento de onda sobre a cicatrização de leitos doadores de enxerto gengival. Estudo clínico, controlado e randomizado

Abstract

This study evaluated the efficacy of dual-wavelength photobiomodulation therapy (PBMT) in the tissue repair process of subepithelial connective tissue graft donor sites. This randomized controlled clinical trial with a parallel design involved 30 patients who were randomly allocated into two groups (n=15) according to the treatment of the wound resulting from the excision of the subepithelial connective tissue graft: CTR Group (n=15): The wound was filled with a fibrin sponge. PBMT Group (n=15): The wound was filled with a fibrin sponge combined with dual-wavelength PBMT applied immediately and at 3, 7, 10, and 15 days post-surgery. Patients were clinically evaluated at baseline and at 3, 7, 15, and 30 days after the surgical procedure. The following parameters were assessed: 1) Percentage of wound reduction through photographic imaging; 2) Degree of wound epithelialization; 3) VAS pain scale; 4) Analgesic consumption. This study observed that dual-wavelength PBMT did not significantly alter wound closure, pain perception, or analgesic consumption by patients. However, wounds treated with PBMT exhibited an accelerated healing process, as indicated by a higher number of epithelialized donor site wounds from the palate within 10 days post- surgery. Dual-wavelength PBMT improved the repair of wounds in gingival graft donor areas on the hard palate.
