Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Objective: To verify if a single LLLT intra or extra oral application, singly, are analogous in their effects in controlling postoperative edema, trismus, pain and wound repair in third molar surgery.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Intra-oral group (IO) will be that in whose participant will receive the LLLT (Photon Lase III DMC equipment) with 660 nm wavelength, 100 mW of power, 107J / cm2 of power density, during 30 seconds, positioning the tip of the laser device in straight contact with each of the four points in the surgical area:
1. corresponding to the occlusal surface of the tooth surgically extracted,
2. in the middle third of the lingual surface, point
3. the middle third of the buccal surface and point
4. retro molar triangle region. Each point will receive energy 3J (Et= 12J).
The extra-oral group (EO) will receive phototherapy with the 808nm of wavelength following the same above protocol although positioning the laser point over the skin in straight contact with four points on the masseter muscle:
1. next jaw insert,
2. lower middle region,
3. upper middle region
4. near the insertion of the zygomatic arch.
In the IO group the extra-oral region will not be irradiated (the laser tip will be put in place without energy) in the EO group it will be done the opposite, so as the same patient will be the control because the participant will not be capable to identify which group he belongs to. The same investigator will perform surgical procedures and laser therapy. All participants will receive the same postoperative medication. Three distances will evaluate the range of edema: from tragus to the corner of the mouth, from gonial angle to the corner of the mouth and from gonial angle to the corner of the eye using a malleable millimeter rule. Trismus will be evaluated by the maximum range of mouth opening considering the inter-incisal distance between the edges of upper and lower right central incisors by a caliper in three moments: before surgery, 24 hours and 8 days after surgery. Participants will be asked to fill in a diary to assess the severity of postoperative pain on a visual analogue pain scale after the end of anesthetic effect: 4, 6, 8, 24, 48 hours postoperatively. The amount and time of medication will be also recorded. The quality of wound repair will be evaluated by two blinded calibrated observers, 24 hours and 8 days postoperatively in score from 0 to 3. The data will be submitted to appropriate statistical analysis for non-parametric samples.
