This study was based on a morphometric analysis of bite marks starting from the quantitative definition of the anterior teeth by the geometric acquisition of the "injuries," using bite marks impressed on pig skin and plastic. Each mark was photographed and acquired. A dedicated program automatically supplied the values of the shape factors and the areas of the pattern geometric figures. The values obtained for the homologous samples were compared to the heterologous values. Statistical comparison was made of the sets by linear regression, determining the correlation coefficient and the determination coefficient for each value. Results showed only 4.8% and 2% of overlap between homologous and heterologous values. This study was carried out in attempting to quantitatively define the anterior teeth of the human dentition and the procedure described and the results obtained support the advantage of morphometric studies and computer-aided programs in this study of bite marks.
本研究基于咬痕的形态测量分析，从通过对“损伤”进行几何采集来定量定义前牙开始，使用印在猪皮和塑料上的咬痕。每个咬痕都进行了拍照和采集。一个专门的程序自动提供形状因子的值和图案几何图形的面积。将同源样本获得的值与异源值进行比较。通过线性回归对数据集进行统计比较，确定每个值的相关系数和决定系数。结果显示同源值和异源值之间只有4.8%和2%的重叠。本研究旨在定量定义人类牙列的前牙，所描述的程序和获得的结果支持了形态测量研究和计算机辅助程序在咬痕研究中的优势。
