本研究的目的在于检查95名29～76岁健康成人,10年时间内几项牙周参数的变化,并分析牙周病进展的危险因素。 作者对上述成人作2次检查,按Ramfjord指效规定,检查牙周退缩(从游离龈缘到釉牙骨质界的距离)、牙周袋深度(从游离龈缘到牙周袋底)和牙周附着水平(牙周退缩与牙周袋深度之差),并对结果作纵向评定。 结果显示,10年期间牙周测定仅有轻度改变,牙周附着丧失与增龄无关,主要是由于牙周退缩的增加,而不是由于牙周袋深度的改变。牙周破坏与一个人的年龄和性别无关。作者指出牙周病不是增龄过程的必然
The purpose of this study was to examine the changes of several periodontal parameters in 95 healthy adults aged 29-76 years within 10 years and to analyze the risk factors for the progression of periodontal disease. The authors performed two examinations of the above adults and examined the periodontal regression (distance from the free gingival margin to the enamel cementum), the periodontal pocket depth (from the free gingival margin to the periodontal pocket), and Periodontal attachment level (difference between periodontal retraction and periodontal pouch depth), and the results were longitudinally assessed. The results showed that there was only slight change of periodontal measurement during 10 years. Loss of periodontal attachment was not related to age, mainly due to the increase of periodontal retraction, not due to the change of periodontal pocket depth. Periodontal destruction has nothing to do with a person's age and gender. The author points out that periodontal disease is not an inevitable process of aging
