目的：准确评估牙周附着体的剩余面积有助于确定牙齿的预后。本研究的目的是确定公式来估计剩余面积的牙周附件水平measurements.Materials and Methods：根30个提取的牙齿，每种牙齿类型的涂层与醋酸乙烯酯溶液和α-氰基丙烯酸酯单体产生的膜。在绘制指南以模拟各种附着水平后移除膜。使用图像分析软件测量每个模拟附着体水平的根尖侧的根表面积。的净或百分比根表面积和相应的附着水平的数据进行了拟合的线性，二次，三次和指数函数和growth curve.Results;线性函数提供了最合适的适合的数据。对于净根表面积，一个陡峭的斜率是明显的牙齿类型具有较大的平均总根表面积。对于百分比根表面积，一个陡峭的斜率是明显的牙齿类型与较短的根length.Conclusions：一个线性函数提供了最合适的公式估计的剩余面积的牙周附着的附着水平测量的基础上。
Aim: Accurate assessment of the remaining area of periodontal attachment assists in determining the prognosis of a tooth. The aim of this study was to determine formulae to estimate the remaining area of periodontal attachment from attachment-level measures.Materials and Methods; Roots of 30 extracted teeth of each tooth type were coated with vinyl acetate solution and alpha-cyanoacrylate monomer to produce a membrane. The membrane was removed after guidelines were drawn to simulate various attachment levels. The root surface area on the apical side of each simulated attachment level was measured using image analysis software. The net or percent root surface area and corresponding attachment level data were fitted to a linear, quadratic, cubic, and exponential functions and a growth curve.Results; The linear function provided the most appropriate fit for the data. For net root surface area, a steeper slope was evident for tooth types with a larger mean total root surface area. For percent root surface area, a steeper slope was evident for tooth types with a shorter root length.Conclusions: A linear function provides the most appropriate formula for estimation of the remaining area of periodontal attachment based on the attachment-level measurement.
