Abstract

Gingival recession is a highly prevalent problem, and may reach 100% of individuals over 50 years old. The presence of the recession may lead to other problems such as tooth sensitivity, esthetic complaints, biofilm accumulation, root caries, and non-carious cervical lesions. To deal with gingival recessions, several surgical techniques have been developed. The most predictable results are achieved by coronally positioned flap (CAF), performed alone or associated with connective tissue graft (CTG). However, even when these techniques are performed, there is a great variation of results in relation to the average of root coverage (range 60-99%). One possible reason to explain this variation is the influence of the local anatomy. However, few studies have given attention on evaluating the possible influence the local anatomy in the outcome of root coverage procedures. Thus, the aim of the present study is to assess the influence of the local anatomy in the percentage of root coverage achieved by two different types pf flap and connective tissue graft to treat gingival recession defect. Forty patients presenting gingival recession will be randomly allocated in two groups: Test Group (n=20), connective tissue graft associated tunnel type flap and the Control Group (n=20), connective tissue graft associates with trapezoidal type flap. The parameters of plaque index (PI), gingival index (GI), gingival recession (GR), will be measured ate baseline and 6 months post-operatively. The tomographic parameters of cord, arch, and arrow, which measure the convexity and to buccal protrusion of the roots, will be measures at baseline and will be used in a stepwise multivariate linear regression analysis as independent variables to test their influence in the root coverage average after six months.
