Low Laser Light Therapy After Impacted Third Molar Removal

Third molars extraction is a surgery frequently performed in dentistry. It is generally associated to a great postoperative distress rendered by pain, swelling and trismus, caused by surgical trauma inflammation. Several methods have been proposed to prevent these complications and to increase tissue repair quality. The use of low level laser therapy (LLLT) has been reported in dentistry since 1970. A large number of studies have reported the benefits of LLLT without collateral damage, positive effect as an anti-inflammatory agent and benefits in accelerating wound repair. However, some clinical applications strategies have been contradictories in everyday practice with results not always equivalent. 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.
