Avaliação clínica da cicatrização de alvéolos irradiados com laser de baixa intensidade com duplo comprimento de onda

Abstract

This study evaluate the effect of dual-wavelength low-level laser therapy (LLLT) on bone and soft tissue repair at sites after lower third molar extraction. For this purpose, 20 patients who underwent extraction of the 2 lower third molars were involved in this study. The post-extraction sockets were treated as follows in a split-mouth model: Test side was treated for irradiation with low intensity laser with dual wavelength (660 nm red laser and 808 nm infrared light) while the control side was not irradiated. The selection of sides that received the treatments occurred randomly. LLLT was applied immediately and 3 and 7 days after the surgical procedure. Alveolar repair was analyzed through clinical analysis at 3, 7, 14, 30 and 90 days after the surgical procedure, considering the occurrence of pain, swelling and bleeding, as well as the quality of the oral mucosa repair, evaluated through visual analogue scale. Clinical analysis showed that LLLT reduced edema and improved oral mucosal repair up to 7 days postoperatively. Dual-wavelength LLLT improved the postoperative clinical course in patients undergoing mandibular third molar extraction.
