Abstract

The aim of this study was to evaluate clinically the use of the Semilunar Coronally Positioned Flap (SCPF) for the treatment of gingival recessions, with or without Enamel Matrix Derivative (EMD). Thirty patients were selected, randomized and allocated in two groups: test (SCPF + EMD) and control (SCPF alone). To attend the study, subjects should present buccal Miller class I gingival recessions with height greater than or equal to 2.0 mm and less than to 4.0 mm in maxillary canines or premolars. Clinical parameters evaluated: gingival recession height (GRH), gingival recession width (GRW), clinical attachment level (CAL), probing depth (PD), height (HKT) and thickness (TKT) of keratinized tissue and papillas height (HP) and width (LP), as well as plaque and gingival index. These data were collected at baseline, 90 days and 180 days after surgery. No statistically significant difference was observed between the groups regarding the reduction of gingival recession after 6 months of follow-up, although a higher percentage of root coverage was found in SCPF + EMD group (91%), when compared to the SCPF (87%) (p> 0.05). Complete root coverage was observed in 60% of the sites of the control group (SCPF alone) and in 66,67% of the sites of the test group (SCPF+EMD). Within the limits of this study it was concluded that SCPF, associated or not with EMD may provide a reduction in gingival recession, with no statistical difference between groups (AU)
