Abstract
BACKGROUND: Suprabony defects are the most prevalent defects and there is very little evidence on their treatment. This study aims to assess the effectiveness of papilla preservation periodontal surgery in the periodontal reconstruction of combined deep intra-suprabony defects. MATERIAL AND METHODS: 20 patients with combined intrabony and supra-alveolar deep periodontal defects treated by papilla preservation periodontal surgery were analyzed. Defects were treated with enamel matrix derivate plus xenograft. Clinical recordings made before surgery and at 12 months. RESULTS: Papilla preservation periodontal surgery showed significant PPD reduction (4.4 ± 1.46 mm; p<0.001), clinical attachment gain (3.35 ± 1.6 mm; p<0.001), increased REC (1.05 ± 0.94; p<0.001), papilla apical displacement (0.85 ± 1.31 mm; p<0.005) and KT reduction (0.5 ± 0.76 mm; p<0.05). At one week, there was incomplete wound closure and necrosis in 40% and 30% of the treated sites, respectively. At one year, the intrabony component filling was 73.65 ± 27.6 % and the supra-alveolar attachment gain indicated an incomplete intrabony defect resolution (-0.15 ± 1.56 mm). CONCLUSIONS: Periodontal pocket was significantly reduced and the level of clinical attachment increased. However, there was significant recession of the gingival margin and the papilla and a trend to incomplete resolution of the intrabony component. Key words:Periodontitis, surgical flaps, reconstructive surgery, regeneration. Copyright:
