Abstract

The objective of this study was to determine which teeth provide the most reliable data for use in age estimation. We studied 170 teeth from the anterior region (central and lateral incisors, and canines) and used an image analysis technique to analyse a number of morphometric features in thin sections of tooth. Our results showed root translucency to be the variable most clearly related to the subject's age, and the canine teeth to provide the most reliable information on this variable.

摘要

本研究的目的是确定哪些牙齿能为年龄估计提供最可靠的数据。我们研究了来自前部区域（中切牙、侧切牙和尖牙）的170颗牙齿，并使用图像分析技术分析牙齿薄片中的一些形态测量特征。我们的结果表明，牙根透明度是与受试者年龄最密切相关的变量，而尖牙能提供关于该变量的最可靠信息。
