This descriptive study compared the healing of mucoperiosteal and "stimulated" osteoperiosteal flaps for the treatment of surgically created periodontal recessions in dogs. Surgically created defects on the canine teeth of 10 healthy mongrel dogs were covered by specially designed, cemented copper bands for 4 weeks (Several maxillary premolar teeth were managed in the same way). A plaque and calculus-promoting diet was fed to the animals during this period. When the bands were removed the diet was altered and an intensive oral hygiene program was instituted. The contralateral tooth, chosen randomly, was utilized for placement of the mucoperiosteal lateral sliding flap and acted as the control. The experimental side was surgically stimulated 21 days prior to elevation of a "stimulated" osteoperiosteal flap for repositioning over the denuded roots. The animals were sacrificed with an overdose of Nembutal and block sections for histologic study were taken at periods ranging from 14 to 50 days. Histologic findings indicate that healing of the stimulated flaps was accompanied by the formation of a relatively short dentogingival epithelium, cementogenesis which varied in amount and type, and new connective fiber insertion into cementum. By contrast, the mucoperiosteal flaps healed with a long dentogingival epithelial relationship and no cementogenesis or connective tissue reattachment.
这项描述性研究比较了黏骨膜瓣和“刺激”骨膜骨瓣在治疗犬类手术造成的牙周袋退缩中的愈合情况。在10只健康杂种犬的犬齿上通过手术制造缺损，用特制的粘结铜带覆盖4周（几颗上颌前磨牙也采用同样方法处理）。在此期间给动物喂食促进牙菌斑和牙结石形成的食物。当去除铜带后，改变饮食并实施强化口腔卫生计划。随机选择对侧牙齿用于放置黏骨膜侧滑行瓣，并作为对照。在掀起“刺激”骨膜骨瓣重新覆盖裸露牙根之前21天，对实验侧进行手术刺激。给动物过量注射戊巴比妥钠使其安乐死，并在14至50天的不同时间段采集组织块进行组织学研究。组织学结果表明，刺激瓣的愈合伴随着相对较短的牙齦上皮形成、数量和类型各异的牙骨质生成，以及新的结缔组织纤维插入牙骨质。相比之下，黏骨膜瓣愈合时牙齦上皮关系较长，且无牙骨质生成或结缔组织再附着。
