本研究旨在对牙周沟/牙槽深度“正常”的牙周部位反复刮治和牙根平整后附着水平的变化进行组织学评估。实验使用了两只猕猴(猕猴)。在6个月的时间里，每隔2周在下颌右侧前磨牙和磨牙的颊面进行一次洁治。对侧牙作为未经处理的对照。治疗结束6个月后(实验开始后1年)处死动物，制作所有实验牙和对照牙的组织学切片。在这些切片上测量牙釉质结合部(CEJ)与结合上皮尖的距离(JE)和JE与牙槽骨脊(BC)之间的距离。结果表明，反复磨削后，结缔组织附着量平均减少0.39 mm，牙槽骨顶相应后退。这一发现与最近临床试验中的观察结果有关，这些临床试验表明，在牙周较浅的位置，反复刮治和根面平整后，临床附着丧失。
The present study was undertaken to enable histological assessment of attachment level alterations following repeated scaling and root planing in periodontal sites with "normal" sulcus/pocket depth. Two monkeys (Macaca cynomolgus) were used. During a period of 6 months, scaling was carried out once every 2 weeks at the buccal surfaces of premolars and molars on the right side of the jaws. The contralateral teeth served as untreated controls. Six months after the completion of treatment (1 year after the start of the experiment), the animals were sacrificed and histological sections of all test and control teeth were produced. In these sections the distances between the cemento-enamel junction (CEJ) and the apical extent of the junctional epithelium (JE) and between the JE and the alveolar bone crest (BC) were measured. The results revealed that repeated scaling and planing resulted in an average loss of connective tissue attachment amounting to 0.39 mm and in a corresponding recession of the alveolar bone crest. The findings are discussed in relation to recent observations from clinical trials demonstrating loss of clinical attachment following repeated scaling and root planing in sites with shallow gingival pockets.
