摘要
目的：了解糖尿病患者牙周炎患牙牙小皮的形态特征。方法：选用糖尿病患者的牙周炎患牙１３颗为实验组，健康上、下颌第一前磨牙１６颗为对照组，用５％硝酸脱钙后切片，伊红染色，光镜观察。结果：实验组所有牙的牙骨质表面均有牙小皮存在，厚度在４０～８０μｍ，从釉牙骨质界向下达根尖处。牙小皮呈规则的板层样结构。对照组１６颗牙的牙骨质表面均无牙小皮存在。结论：糖尿病患者牙周炎患牙的牙骨质表面有异常的牙小皮存在。
Objective: To determine the nature of the dental cuticle found on teeth with diabetic periodontitis. Methods: Thirteen permanent teeth which were extracted from three diabetic patients with periodontitis were studied, with the control group of 16 healthy teeth extracted for orthodontical reasons, then all the teeth were decalcified with 5% nitric acid, stained with HE, and examinated by using light microscope. Results: A layer of thick coat, dental cuticle, covered the root surface of the teeth with diabetic periodontitis, and the cuticle which presented regular laminar structure extended from the cementoenamel junction to the apical portion with different thickness from 40 to 80 μm, but no such similar cuticle structure was found on the healthy teeth of the control group. Conclusion: There is abnormal cuticle structure on the teeth of diabetic patients with periodontitis.
