About this trial
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.
Eligibility criteria
Qualifiers
Patients who present retained lower third molars, according to the degree of surgical difficulty of the procedure and the anatomical position.The selected molars will be those classified according to classes II and III and/or B or C of Pell and Gregory Classification; in vertical or mesio-angular position, according to the Winter Classification or Class II with need for ostectomy or III, with need for ostectomy and odontosection of the Prant Scale, modified by Amarillas-Escobar et al.
That have an indication for the extraction of the lower third molars (due to recurrent infections, bad anatomical position, orthodontic indication) or a professional indication presented in writing and that are healthy (ASA I, with a negative medical history).
Male or female gender.
Age between 18 and 50 years.
Disqualifiers

Presenting absence of upper and lower central incisors,
