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%.
Knowing the ability of the low-power laser to provide the body with an improvement in inflammatory response, with consequent reduction of edema, minimizing painful symptoms and leading to biostimulation, laser therapy is presented as an alternative for processes that present an inflammatory reaction, Pain and need for tissue regeneration. The literature shows the efficacy of laser in the postoperative surgery for extraction of third molars. However, to date, there is no consensus on the best protocol to be used in these cases. Thus, the objective of this study will be to evaluate two laser application protocols. To this end, 60 patients will be selected who require surgical treatment for the extraction of third molars, regardless of race or gender, between the ages of 16 and 40, from the School 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 10 J (30 mW, 10 J / cm 2) and group 3 - control group, with application of placebo laser. At 3 and 7 days after surgery, patients will be evaluated by two evaluators who will measure edema, mouth opening (assessment of muscle spasm) and pain. To compare the data, we will use the analog pain scale (VAS), the method of Ustün et al. (2003), and the millimeter rule. The patient will also be questioned about possible postoperative problems, as well as the surgeon, who will classify the postoperative repair process according to Batinjan et al. (2013). 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%.

A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
Disturbances in the normal fluency and time patterning of speech that are inappropriate for the individual's age and language skills. (DSM-V)
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as in LASER THERAPY. These non-thermal effects are thought to be mediated by a photochemical reaction that alters CELL MEMBRANE PERMEABILITY, leading to increased mRNA synthesis and CELL PROLIFERATION. Low-level laser therapy has been used for a wide variety of conditions, but most frequently for wound healing and pain control.
