Chronologic age is an utmost important birth record in many industrialized Western countries. When the date of birth is unknown, there is a demand for establishing the chronologic age. Dental methods for age estimations are considered more reliable than most other methods by the majority of researchers and are among the most commonly used means to determine age. Traditionally, these methods have most often been based on subjectively estimated, radiographic stages of tooth development. In the present study metric measurements of the length of the forming root have been used and are compared with one standard method. The formed part of the root of the lower third molar as seen in a panoramic radiograph was digitized. Data were directly stored in a computer for subsequent statistical analysis. The technique of collecting data with the aid of a computer had some statistical advantages. The precision of age estimations was, however, slightly inferior to the standard method.
在许多西方工业化国家，实足年龄是极其重要的出生记录。当出生日期未知时，就需要确定实足年龄。大多数研究人员认为，用牙齿来估计年龄的方法比大多数其他方法更可靠，并且是最常用的确定年龄的方法之一。传统上，这些方法大多基于对牙齿发育的放射学阶段进行主观估计。在本研究中，使用了对正在形成的牙根长度的测量指标，并与一种标准方法进行了比较。在全景X光片中看到的下颌第三磨牙牙根的形成部分被数字化。数据直接存储在计算机中以便后续进行统计分析。借助计算机收集数据的技术具有一些统计学优势。然而，年龄估计的精度略低于标准方法。
