| 摘 要： | 目的:检测各牙位牙周膜面积及不同附着水平与剩余牙周膜面积间的变化规律,探讨牙周附着丧失与牙周支持能力及牙周病预后判定间存在的可能联系。方法:收集除第三磨牙外不同牙位的离体牙420颗,在釉牙骨质界根方牙面涂以成膜材料以模拟牙周膜,在模拟膜表面平行于釉牙骨质界处描记出不同附着水平的高度线,经扫描仪扫描剥离的模拟牙周膜,再经计算机图像处理软件PhotoshopCS29.0和Scion Image4.0.3和SAS6.12软件包进行面积数据分析。结果:各牙位牙周膜面积对应不同附着水平间的数值变化规律满足一次函数的回归检验(P<0.001)。根据所得回归直线,当附着丧失超过5.37mm时,各牙位剩余牙周膜面积多降至原有面积的50%以下。结论:各牙位根面牙周膜面积随附着丧失增加而递减的变化规律与一次函数曲线最为拟合;多数牙位的附着水平在丧失超过5.37mm时,其剩余牙周膜面积已不足正常值的一半,不再具备提供额外牙周支持力的条件。

| Abstract: | PURPOSE:To estimate the total periodontal ligament areas and the remaining periodontal ligament areas from different attachment level of each tooth type,and to determine the relationship between the attachment loss and the prognosis of periodontal diseases. METHODS:Four hundred and twenty extracted teeth (30 of each tooth type of one side of both arches,except for the third molar) were collected.The root surface of each tooth was coated with polyvinyl alcohol to produce a membrane after cleaning. The membra... |
