Résumé
Various methods, including clinical and radiographic techniques, can be used to assess periodontal regeneration in interproximal areas. The goal of the present study was Periodontal regeneration; to compare the papilla length relative to the alveolar bone crest measured by clinical, intrasurgical, Radiographic bone length; and radiographic techniques. Bone probing length; Materials and The study sample included 250 interproximal papillae in 68 patients with Actual papilla length generalized chronic periodontitis. The papilla length from the alveolar bone crest was measured clinically [as the actual papilla length, APL], intrasurgically [as the bone probing length, BPL], and radiographically [as the radiographic bone length, RBL]. Measurements were standardized by using acrylic resin stents, XCP rinn, a paralleling technique, and/or a radiographic grid. The mean [+/- standard deviation] for RBL was 4.9 +/- 0.8 mm, BPL was 5.1 +/- 0.6 mm, and APL was 5.1 +- 0.6 mm. Correlations between RBL and APL and between BPL and APL were 0.918 and 0.943, respectively [both P < 0.01]. If the clinical recordings are appropriately standardized, then noninvasive radio-graphic methods can be used to evaluate the papilla length with good accuracy
