Resumo:
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.
