Summary

Introduction: Previously published studies report a prevalence ranging from 35.9% to 58.7% of the general population with at least one impacted wisdom tooth. Surgical extraction of wisdom teeth is the procedure most often associated with postoperative complications, such as pain, swelling, trismus, and oral discomfort during the first postoperative days. These complications arise from an inflammatory response, which is a direct and immediate consequence of the surgical intervention and can limit the patients' daily functions in the recovery phase and compromise their quality of life. Several methods have been used to control postoperative morbidity related to wisdom tooth extraction, including administration of proteolytic enzymes, tube drains, cryotherapy, anti-inflammatory and analgesic drugs and low level laser therapy. Objectives: To test whether the use of low power laser can improve post-operative pain, swelling and healing of the surgical wound. Material and methods: A double-centre, randomised, split-mouth, double-centre clinical study will be carried out in 38 patients per centre, totalling 76 patients and 152 wisdom teeth, who will undergo surgery for the extraction of the lower third molars. The necessary data for the study will be taken on the days of the consultation for surgery planning, on the day of surgery, by the patient on each post-operative day and on the 7th post-operative day (at the time of suture removal ).

Conditions

• Third Molar Extraction
• Oral Pain
• Tooth Extraction

Interventions

Type	Name	Description
RADIATION	Low frequency laser activated photobiomodulation	Protocol description Infrared: analgesia, biostimulation of tissues, edema and hyperemia (hard and soft tissues). There will be 11 laser application points, 3 intra-oral and 8 extra-oral, with a total dose of 33J. Intraoral: one point in the region of the mandibular lingula (point of submersion of the mandibular nerve), one vestibular point and one lingual point in relation to the alveolus of the extracted wisdom tooth. Extraoral: for muscle relaxation, five points on the masseter muscle; for oedema drainage, one point in each lymph node region: parotid, submandibular and buccal.
OTHER	Low frequency laser photobiomodulation inactive	The same protocol as the activated group
