Summary

The objective of the present study will be to evaluate the efficacy of photobiomodulation (PBM) with LED in pain control, facial edema, paresthesia, bone repair and quality of life arising after maxillar surgical disjunction (MSD). A randomized, double-blind, placebo-controlled clinical trial involving 72 participants aged 18 to 45 years, who search the Service of Oral Maxillofacial Surgery and Traumatology of the Mandaqui Hospital Complex to undergo MSD, attend to the eligibility criteria and agree to participate. Surgeries will be conducted by three oral maxillofacial surgeons who will perform all surgical procedures, two examiners (who will perform pre and post-surgical evaluations, blinded to the experimental group) and another researcher who will perform the LED application. Before the surgeries, facial measures, radiographic examinations, tests of facial and oral sensitivity and the evaluation of the level of anxiety of all the participants will be carried out. Immediately after the surgeries, the participant will be inserted into the placebo group or the LED group, according to block randomization defined previously. In the LED group, the participants will receive PBM with an extraoral device (660 and 850 nm with 6J per point) and an intraoral one (660 nm with 2J per point) and in the control group the participants will be attended in the same way, but with the LED devices kept off. The applications will be in the immediate postoperative period, 1, 2, 7, 14, 30, 60, 90 and 120 days after the end of the surgeries, when the evaluations will also be performed. Facial measurements, extra and intraoral sensitivity, pain and bone repair will be evaluated. Secondarily, the data regarding the occurrence of headache; otalgia; nausea; bruise; nasolacrimation; epistaxis; dysphagia; systemic and superficial temperature in the operated region; use of analgesics and anti-inflammatories; anxiety and impact of oral health on the participants' quality of life will be computed.

Interventions

Type	Name	Description
RADIATION	Photobiomodulation	PBM will be applied with extra and intraoral LED devices. The LED plates speed up the treatment as they deliver all the energy at once, having the advantage of radiating several points at the same time. The applications of both will occur in the following experimental periods after the end of the surgeries: immediate postoperative, 1, 2, 7, 14, 30, 60 and 90 days.
RADIATION	Placebo Photobiomodulation	The person responsible for applying the PBM will simulate the irradiation by positioning the devices in the same locations described for the PBM group, but the equipment will be kept off
