RESUMO

The aim of the present study was to evaluate the clinical response of proximal furcations treated with enamel matrix derived proteins (EMD). Twenty four patients with at least one class II proximal furcation involvements presenting probing depth (PD) ? 5 mm and bleeding on probing were selected. The patients were randomly assigned to: Control Group (n=20) ? Open Flap Debridement (OFD) + EDTA 24% conditioning (PrefGel®); Test Group (n=20) ? OFD + EDTA 24% conditioning + EMD application (Emdogain®). Plaque Index (PI), Bleeding on Probing (BOP), Probing Depth (PD), Gingival Margin Position (GMP), Relative Vertical and Horizontal Clinical Attachment Level (RVCAL and RHCAL, respectively), Vertical and Horizontal Bone Level (VBL and HBL) and Furcation Closure were evaluated immediately before and 2, 4 and 6 months after the surgeries. At 6th month the gain of RVCAL of control and test group were 0.63 e 0.74 mm, while the RHCAL gain were 1.13 e 1.64 mm, both without statistical difference between the groups. The VBL and HBL gain of control and test group were 0.98 and 0.85 mm and 0.94 and 1.08 mm respectively, also without statistical difference. Four closed furcations were observed at 6th month in the test group, while no closed furcations was observed at control group (p<0.05). It could be conclude that, although the proximal furcations showed similar gains of RVCAL, RHCAL, VBL and HBL at 6th month, the EMD application promote a superior, but unpredictable, frequency of closed furcations than that found with open flap debridement and EDTA 24% conditioning
