Preventive Effect of Photobiomodulation in the Postoperative Period of Extractions of Retained Lower Third Molars
Evaluation of the Preventive Effect of Photobiomodulation in the Postoperative Period of Extractions of Retained Lower Third Molars: a Double-blind Randomized Controlled Study
University of Nove de Julho

Nov 20, 2023
INTERVENTIONAL
Conditions
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.

Interventions
Intra-oral irradiations wll be performed with a low intensity Laser device at 4 anatomical points, with a wavelength of 660 nm. The extraoral FBM will be applied with 1 cluster (20cm2) with a wavelength of 630nm. Subsequently, the same region will be irradiated with the same cluster, using the 4 LEDs with a wavelength of 850 nm 1 hour before performing the surgery.
Participants will receive 1 hour before the surgery a placebo tablet, with the same physical and organoleptic characteristics, composed of corn starch, without harmful effects on health and simulating Dexamethasone (Celsius Laboratory, Montevideo, Uruguay).).
The irradiation simulations will be practiced in the same anatomical points described in the experimental group. This protocol will be carried out 1 hour before the surgical procedure (Baseline). The Laser device will be disconnected and its beep sound will be recorded and run on simulating the irradiation.
The patients will receive Dexamethasone 8 mg (Corodex, Laboratorio Celsius, Montevideo, Uruguay) PO 1 hour before surgery (Almeida et al 2019)
