Controle da dor em pacientes submetidos à gengivectomia/gengivoplastia com laser de baixa intensidade.

Abstract

The objective of this study was to evaluate the efficiency of Laser Low Intensity (LBI) in controlling pain and reducing analgesic consumption after periodontal surgery gingivectomy and gingivoplasty. We selected 20 patients with gingival hyperplasia, which were randomly divided into two groups with 10 individuals each. In the test group was applied after gingivectomy / gingivoplasty, low intensity laser in the surgical wound and analgesic prescription only in case of pain; while the control group was only performed analgesic therapy, in case of pain without the application of laser after surgery. In the test group, the laser light was irradiated by 3 points, feces mesial, distal and vestibular of the components involved in periodontal surgery. Irradiation was performed in a single session, for 30 seconds at each point, with a diode laser (808 nm, 100W, 105J / cm 2). Postoperatively of 5 hours and 1o, 2o, 3o, 4o, 5o, 6o and 7o days, they assessed pain using a visual analog scale (VAS) and analgesic amount of ingested by the patient. In the laser group, 80% of subjects reported no postoperative pain and those who reported was mild discomfort (VAS = 1). In no laser group, pain was present in more patients (60%) and was more intense (VAS = 3). ). The data analysis showed a statistically significant difference when comparing the greatest pain felt in the postoperative period between groups (p = 0.26). However, there was no difference in evaluating the intake of painkillers. It follows that the LBI therapy decreases the intensity of postoperative pain and periodontal surgery Gingivectomy and gingivoplasty. However, it is suggested studies with a larger sample size to confirm these data and generalize these findings.
