BACKGROUND: In this study, we compare the effectiveness of enamel matrix derivative (EMD) associated with a simplified papilla preservation flap (SPPF) technique to SPPF alone when surgically treating supra-alveolar-type defects. METHODS:Fifty patients, from 54 initially selected, presenting horizontal bone loss around ≥4 adjacent teeth, were treated by an SPPF technique; 25 participants also receivedEMD (test group) and 25 patients underwent flap surgery alone (control group). A complete clinical and radiographic examination was performed at baseline and 12 months after treatment. Pre- and post-therapy probing depth (PD), clinical attachment level (CAL), gingival recession (GR), and radiographic bone level (BL) were compared between treatments. RESULTS: After 12 months, PD, CAL, and GR in both groups showed significant differences from baseline (P <0.001). No differences in BL scores were observed within the groups at the 12-month examination. After 1 year, the test group showed significantly (P <0.001) greater PD reduction (3.4 ± 0.7 mm) and CAL gain (2.8 ± 0.8 mm) and a smaller GR increase (0.6 ± 0.4 mm) compared to the control group (PD, 2.2 ± 0.8 mm; CAL, 1.0 ± 0.6 mm; GR, 1.2 ± 0.7 mm.) BL changes did not significantly differ between the experimental groups. CONCLUSION: The results of this study suggest that combining EMD and SPPF in the treatment of suprabony defects may lead to a greater clinical improvement compared to SPPF alone.
