Gingival recession is the apical shift of the gingival margin leading to root surface exposure. The presence of gingival recession can cause other negative effects, such as root sensitivity, esthetic demand and cervical wear. Because of these problems cause by gingival recession, there are many surgical techniques aimed to deal with recessions. Among all available surgical procedures, the connective tissue graft is the most predictable and the one presenting better long term results. However, this procedure has been related to greater mobility and post-surgical pain compared to other techniques because it requires a second surgical site in order to harvest the graft. There is no study available in the literature evaluating the effects of low intensity laser therapy (LILT) on the wound healing process of the donor site (palate) of CTG procedure. For this, 20 individuals presenting gingival recession will be randomly divided in 2 groups: Test Group: CTG procedure for root coverage and LILT application at the donor site, and Control Group: CTG procedure alone. The clinical and photographic parameters will be evaluated: Defect Area (DA); presence of scars (S); tissue colorimetric evaluation (TC); post-operative pain (P). Intragroup and intergroup evaluation will be performed using significance of 5%. (AU)
