Abstract

Gingival recession is a highly prevalent problem and can reach up to 100% of individuals over 50 years of age. The presence of the recession may result in the occurrence of other problems such as dentin hypersensitivity, esthetic complaints, biofilm accumulation, root caries, non-carious cervical lesions among others. The aim of this study was to compare clinically, esthetically and patient-centered parameters, two types of flap designs for connective tissue graft in the treatment of gingival recession. Were selected forty two patients presenting with gingival recession divided in the test group: periodontal surgery for root coverage using the tunnel flap and graft of connective tissue and control group: trapezoidal flap and graft of connective tissue. Clinical, esthetics, and comfort of patients parameters were assessed at 45 days, 2, 3 and 6 months after the procedure. After six months, the control group presented mean root coverage of 87.2±27.1 % while the test group presented a mean of 77.3±20,4 % with significant difference between groups. The complete root coverage was achieved in 71.42 % of recessions treated with trapezoidal flap and 28.57 % of recessions treated with tunnel flap, with a statistically significant difference between groups. The average of RES was 8.42 ± 1.5 for the T + CTG group and 7.81 ± 1.91 for the E + CTG group after treatment with no difference between groups. The VAS scale analysis showed a lower morbidity associated to tunnel technique (p = 0.04). It can be concluded that the trapezoidal flap technique was more effective than the tunnel flap technique in achieve the root coverage. However tunnel technique was associated with better gingival texture and patient comfort being a valuable treatment option. (AU)
