The effect of Low Power Laser on Pain reduction, Mouth Opening Difficulty and Swelling after wisdom teeth Removal

INTERVENTION: E06.892 Split mouth study. Lower third molar extraction in both the test group and the placebo group. In the test group, a low‐power laser will be applied using infrared technology, with a wavelength of 808nm +/‐ 10nm, fiber diameter 600µm, spot 0.0028 cm2, irradiation dose of 3J/cm2, power of 100 mW, 40s application time per point. Eight application points were determined, being 4 external (TMJ region, branch region, angle region and mandible body region) and 4 internal (2 in the lateral pterygoid region and 2 in the surgical wound region). We emphasize that for each new application the same protocol described above will be followed. Apparatus called Therapy XT (São Carlos/SP, Brazil) and with infrared technology with a wavelength of 808nm +/‐ 10nm and red technology with a wavelength of 660nm +/‐ 10nm. In the control group, the laser application will not be performed. CONDITION: Teeth included PRIMARY OUTCOME: It is expected to find a reduction in morbidities after third molar removal surgery, verified through data collection methods in relation to the patient's maximum mouth opening, demarcation of anatomical points to check edema and amount of analgesic pills ingested to check the from this, statistical tests were performed with a confidence interval of 95% and the value of the probability of significance less than or equal to 0.05. SECONDARY OUTCOME: Secondary outcomes are not expected INCLUSION CRITERIA: Patients older than 18 years old, who require extraction of both lower third molars; Patients who are classified by the American Society of Anesthesiology (ASA, from the English American Society of Anesthesiologists) as ASA I.
