Fotobiomodulação em cirurgia periodontal: relato de caso clínico

Abstract

INTRODUCTION: Photobimodulation (FBM) with low power laser has been gaining more and more space in dentistry, especially to stimulate repair, accelerate healing, modulate inflammation. In this sense, FBM can be used in periodontal surgeries, helping in the postoperative period of these procedures, however, there is little evidence of the use of this technology in this important area of ​​dentistry. OBJECTIVES: To report a clinical case of periodontal surgery, in which photobiomodulation was used aiming at a more comfortable postoperative period. METHODOLOGY: This study is a descriptive case report study. RESULTS: A 22-year-old female patient complained of aesthetic discomfort due to the large gingival exposure when smiling. After diagnosis and digital planning, the patient underwent crown augmentation surgery. Immediately after the surgical step, the patient underwent FBM, which consisted of using a low-power laser at red (660nm) and infrared (808nm) wavelengths. Infrared laser irradiation was performed on attached gingiva, buccally, close to the apex and cervical third of each tooth involved in the surgery, at a power of 100mW, 2J per point, energy density of approximately 66J/cm2 for 20 seconds. The red laser was used on the vestibular papillae, attached gingiva, close to the mucogingival line of the teeth, at a power of 100mW, 1J per point. After that, the red laser protocol was repeated after 3 and 7 days postoperatively. The patient reported mild and provoked pain during feeding or touch and reports that the prescribed analgesic was not needed. CONCLUSION: Through the present case, we conclude that FMB is an important method for the treatment of periodontal surgeries, as it has numerous benefits, including healing and analgesia.
