观察了猴牙周再生组织与手术暴露牙根面连接处的超微结构特征。每隔1至18个月对样本进行研究。所有时间间隔的标本均显示牙本质和牙骨质表面的交界上皮再生。上皮再附着存在于完整的，以及改变根面。在所有样本中也观察到牙骨质再生，但通常仅限于伤口的最顶端部分。牙骨质在牙本质上形成，牙骨质也是如此。在新生牙骨质和手术暴露的牙本质或牙骨质的界面处经常观察到致密的颗粒层，可能具有多糖-蛋白质性质。人工分裂，显然发生在组织处理的脱矿阶段，经常涉及这个颗粒层。这表明，这些分裂的处理结果，并不反映缺乏凝聚力或粘附再生牙周组织内。本研究得到了美国公共卫生署，宾夕法尼亚大学口腔健康研究中心（批准号DE-02623）的支持。感谢Rollande Tremblay小姐和J.

The ultrastructural features of the junction between regenerated periodontal tissues and surgically exposed root surfaces were investigated in monkeys. Specimens were studies at intervals of 1 to 18 months. Specimens at all time intervals demonstrated regeneration of the junctional epithelium to both dentin, as well as cementum surfaces. Epithelial reattachment was present on intact, as well as altered root surfaces. Cemental regeneration was also noted in all specimens, but ap‐ peared generally confined to the most apical portion of the wound. Cementum formed over dentin, as well as cementum. A dense, granular layer, possibly of a polysaccharide‐protein nature, was frequently noted at the interface of new cementum and the surgically exposed dentin or cementum. Artifactitious splits, apparently occurring during the demineralization phase of tissue processing, frequently involved this granular layer. It is suggested that these splits result from processing and do not reflect a lack of cohesion or adhesion within the regenerated periodontium. This investigation was supported by the United States Public Health Service, Center for Oral Health Research, University of Pennsylvania, Grant No. DE‐02623.
