Emprego do Laser de baixa Intensidade no pós-operatório de Exodontia de Terceiros Molares

Abstract

The present investigation, a double-blind randomized split-mouth study, aimed to evaluate the effects of low-intensity laser use in the postoperative period of patients submitted to third-molar impacted extraction. To that end, 10 volunteers of both genders, between 16 and 26 years old, without local or systemic pathologies, exhibiting bilaterally impacted lower third molars, with similar disposition and indicated extraction, underwent surgeries to remove them. The surgeries were always performed by the same operator with a minimum interval of 21 days. For the procedures, the participant received a capsule of nimesulide 100mg 10 minutes after the end of the surgery, with maintenance dose of 12x12 hours for 3 days. In one of the groups, after anesthesia and suturing, red laser 660 nm was used, with a dose of 3 joules per 30 seconds in these two surgical times on the buccal and lingual surfaces of the operated region, and in the postoperative period of 24 and 72 hours. The 808 nm infrared laser with a dose of 3 joules per 30 seconds was also applied in the submandibular, submental and cervical lymph nodes soon after surgery and in the postoperative period of 24 and 72 hours as an indication of drainage of the inflammatory markers. After statistical analysis, performed using the paired t-student test, the results showed a significant difference between the experimental sides, showing improvement in postoperative pain, reduction of edema and limitation of mouth opening on the side where the laser was applied . The low-intensity laser showed to be efficient in the postoperative period of third molar impacted extraction.
