Preventive Effect of Photobiomodulation in the Postoperative Period of Extractions of Retained Lower Third Molars

Molar, Third Clinical Trial

Official title: Evaluation of the Preventive Effect of Photobiomodulation in the Postoperative Period of Extractions of Retained Lower Third Molars: a Double-blind Randomized Controlled Study

Status Not yet recruiting

Clinical Trial Summary

Third molar extraction is one of the most performed surgical procedures in Dentistry. A comfortable postoperative period and rapid return to daily activities increase the need to control the inflammatory response and its signs and symptoms such as pain, edema, and lockjaw. Therefore, the objective of this study is to evaluate the efficacy of the prophylactic use of Photobiomodulation in the reduction of edema in the postoperative period of extractions of retained lower third molars.The primary study variable will be postoperative edema measured in millimeters, 48 hours after surgery, and the secondary variables will be: pain, lockjaw, local temperature (measured with a thermographic camera), dysphagia, and the need to ingest nonsteroidal analgesics (Acetaminophen)These variables will be evaluated at the beginning of the study (baseline), at 2 and 7 days post-surgery. All adverse effects will be recorded. The data obtained will be represented by their means ± SD and the p value will be set at 0.05.

Clinical Trial Description

Third molar extraction is one of the most performed surgical procedures in Dentistry. A comfortable postoperative period and rapid return to daily activities increase the need to control the inflammatory response and its signs and symptoms such as pain, edema, and lockjaw. To control these events, the prophylactic use of anti-inflammatory steroids has been widely recommended by some authors. However, there is no strong evidence on the real benefits of its use as opposed to its possible side effects. Photobiomodulation has proven to be a good alternative when applied in the postoperative period to control pain, edema and lockjaw. On the contrary, its application prior to a procedure of this type has not been sufficiently evaluated. Therefore, the objective of this study is to evaluate the efficacy of the prophylactic use of Photobiomodulation in the reduction of edema in the postoperative period of extractions of retained lower third molars. Healthy individuals (ASA I), who have an indication for extraction and are included in the study, will be randomly divided into two groups: Control Group: with the administration of prophylactic Corticosteroid (Dexamethasone 8 mg/ 1h before surgery), and the simulated application of Photobiomodulation, under the same protocol as the Study Group and Study Group: to which Photobiomodulation will be applied by means of intraoral Low Intensity Laser with wavelengths of 660nm and 808nm applied at 4 anatomical points (power of 0.1W, radiant exposure of 1,061 J/cm2 and energy of 3J per point and an application time of 30 seconds, totaling 12J of energy). Besides, the extraoral application will be carried out with a cluster device of combined LEDs with a total exposure area of 20cm2, which will be composed of 5 LEDs with a wavelength of 630nm (power of 0.25W per LED, a radiant exposure of 3 J /cm2 and energy of 12 J per LED spot, with an exposure time of 48 seconds) and 4 LEDs with a wavelength of 850 nm (power of 0.3W per LED, a radiant exposure of 2.4 J/cm2 and an energy of 12J per LED point, and an exposure time of 40 seconds). The Study Group will be administered a placebo tablet simulating Dexamethasone, also 1 h before the surgical procedure. The primary study variable will be postoperative edema measured in millimeters, 48 hours after surgery, and the secondary variables will be: pain, lockjaw, local temperature (measured with a thermographic camera), dysphagia, and the need to ingest nonsteroidal analgesics (Acetaminophen) after the first 3 postoperative days, where Ketorolac 10 mg will be administered orally, in a regulated manner. These variables will be evaluated at the beginning of the study (baseline), at 2 and 7 days post-surgery. All adverse effects will be recorded. The data obtained will be represented by their means ± SD and the p value will be set at 0.05.
