Low Power Laser in Mandibular Third Molar Surgery

The low-power laser provides the body with an improvement in the inflammatory response. Thus, the objective of this study is to evaluate two laser application protocols in 60 patients requiring surgical treatment for extraction of third molars included, without distinction of race or gender, aged between 16 and 40 years, coming from the Faculty of Dentistry Of São José dos Campos (UNESP). These patients will be divided randomly into 3 groups: group 1 - intraoral irradiation with 660 nm laser at a dose of 10 J (30 mW, 10 J / cm 2) , group 2 - intraoral irradiation with 660 nm laser at a dose of 30 J (30 mW, 30 J / cm 2) and group 3- control group, with application of placebo laser. At 3 and 7 days after surgery, the patients will be evaluated by two evaluators who will measure edema, trismus and pain. The tissue repair will also be evaluated after 1, 3 and 6 months of surgery, through radiographic analysis and periodontal conditions in the distal of the lower second molar. The results will be submitted to descriptive statistics and compared using the statistical analysis of variance (ANOVA) and Tukey test with significance level of 5%.
