The purpose this study was to test for short-term clinical differences in periodontal status after treatment with osseous recontouring and flap curettage in humans. Twelve systemically healthy patients with bilaterally similar marginal periodontal destruction received a standardized regime of presurgical therapy. The posterior segments of these patients were then treated with osseous recontouring and flap curettage. The investigators assigned the segments in one jaw at random to osseous recontouring and flap curettage, and then reversed the sides receiving surgical treatment in the opposing jaw. Postsurgical photographs and measurements for supragingival plaque, tooth mobility, gingival inflammation and periodontal attachment levels relative to the cemento-enamel junction were made for 6 months. Statistical analysis revealed that: (1) osseous recontouring and open flap curettage equally reduced plaque and gingival inflammation; (2) each surgical procedure equally increased attached gingiva; (3) pocket reduction achieved with osseous recontouring was maintained over 6 months, pockets recurring after open curettage; (4) open curettage did not induce bone regeneration; (5) osseous recontouring did not result in irreversible tooth mobility; (6) osseous recontouring resulted in a net loss of attachment; open curettage producing a net gain, especially in deeper pockets; and (7) both procedures improved periodontal health.
本研究的目的是测试人类在接受骨轮廓重塑和翻瓣刮治术后牙周状况的短期临床差异。12名全身健康且双侧边缘牙周破坏相似的患者接受了标准化的术前治疗方案。然后对这些患者的后牙段进行骨轮廓重塑和翻瓣刮治。研究人员将一侧下颌的牙段随机分配接受骨轮廓重塑和翻瓣刮治，然后在对侧下颌反转接受手术治疗的部位。术后6个月拍摄了照片，并对龈上菌斑、牙齿松动度、牙龈炎症以及相对于牙骨质-釉质界的牙周附着水平进行了测量。统计分析显示：（1）骨轮廓重塑和开放性翻瓣刮治同样能减少菌斑和牙龈炎症；（2）每种手术操作同样能增加附着龈；（3）骨轮廓重塑实现的牙周袋减少在6个月内得以维持，开放性刮治后牙周袋会复发；（4）开放性刮治不会诱导骨再生；（5）骨轮廓重塑不会导致不可逆的牙齿松动；（6）骨轮廓重塑导致附着净损失；开放性刮治产生净增益，尤其是在较深的牙周袋中；（7）两种手术操作均改善了牙周健康。
