目的根据腭皱的形态图特征,进行口腔腭皱在法医学同一认定的指标体系构建。方法收集100例成年人腭皱模型,依据腭皱的形状、数量、位置分布等特征对腭皱形态图进行全面系统的编码。编码顺序采用英文字母按照先右侧再左侧,先前部再后部的顺序编码,并且右、左侧编码以破折号连接。最后依据编码,统计分析腭皱形态分布特征。结果 100例腭皱形态图中,个体间未见完全一致者,每个个体不论男性与女性均表现有独特的腭皱形态图;且同一个体左右侧单条腭皱的形态及分布亦不同。波浪形腭皱所占比例最大(23.03%),三分叉形出现比例最小(0.74%),不同性别的波浪形及曲线形腭皱所占比例均较大,女性波浪形(22.7%)及曲线形(18.28%);男性波浪形(24.11%)及曲线形(21.43%)。结论口腔腭皱法医学同一认定的指标体系构建,将为法医学的同一认定提供一种新的方法。
Objective According to the morphological features of palatal fold, the construction of the index system for the same identification of oral palatal fold in forensic science was performed. Methods A total of 100 adult palatal wrinkles were collected and systematically coded according to the shape, number and location of the palatal fold. The encoding order is English alphabetical order according to the order of the first right and then the left, the first and the second, and the right and left codes are connected by a dash. Finally, according to coding, statistical analysis of palatal wrinkles distribution characteristics. Results There was no complete agreement between palatal palates in 100 cases. Each paired individuals showed unique palate pattern, both male and female. The shape and distribution of single palatal fold on the left and right sides of the same individual were also different. The percentage of wavy cleft palate (23.03%) was the lowest (0.74%), and the proportion of wavy cleft palate and cleft palate (22.7%) and Curvilinear (18.28%); Men wavy (24.11%) and curvilinear (21.43%). Conclusion The establishment of the index system for the same identification of oral palate wrinkles will provide a new method for the same identification of forensic medicine.
