Utilizing a nonhuman primate model, a study was carried out to determine the nature of the attachment between the tooth and the gingival tissues following periodic root planing and soft tissue curettage. Under the conditions of this investigation, periodic root planing and soft tissue curettage combined with thrice weekly plaque control resulted in the formation of a long junctional epithelium with no new connective tissue attachment. In eight of the 22 experimental pockets, however, this procedure produced discontinuities or "windows" in the junctional epithelium. The coronal attachment of gingival tissues to the root surface (increased resistance to probing) commonly reported following root planing and soft tissue curettage appears to result from the formation of a long junctional epithelium rather than new connective tissue attachment.
利用非人类灵长类动物模型，开展了一项研究以确定在定期进行根面平整和软组织刮治后牙齿与牙龈组织之间附着的性质。在本研究条件下，定期根面平整和软组织刮治结合每周三次的菌斑控制导致形成了长结合上皮，且无新的结缔组织附着。然而，在22个实验性牙周袋中的8个中，该操作在结合上皮中产生了连续性中断或“窗口”。根面平整和软组织刮治后通常报道的牙龈组织向牙根表面的冠向附着（探诊阻力增加）似乎是由长结合上皮的形成而非新的结缔组织附着导致的。
