目的：通对X线曲面断层片不同牙列区域进行观测，全面筛选颌面影像法医同一认定的定性识别指标，为建立颌面部的同一认定信息数据库提供基础。方法随机选择X线曲面断层片800张作为研究对象，根据牙齿、颌骨及其毗邻结构的生理解剖特征、病理变化特征和牙齿的各种治疗特征进行初级编码和分级编码，统计其牙列编码的多样性。结果600张X线曲面断层片（牙齿或治疗或没有治疗）全口牙列、上颌、下颌牙列的多样性分别为90．7%、74．8%、74．3%，右上、左上、右下、左下后牙区编码的多样性分别为68．8%、69．3%、63．7%、66．8%，前牙区、上前牙区、下前牙区的多样性分别为24．3%，25．7%、17．8%。200张牙齿有治疗史者的X线曲面断层片全口牙列、上颌、下颌牙列编码的多样性分别为99．0%、98．0%、98．5%。右上、左上、右下、左下后牙区编码的多样性分别为96．5%、97．5%、98．5%、97．5%，前牙区、上前牙区、下前牙区牙列编码的多样性分别为54．0%、51．5%、59．5%。结论应用全口、单颌或后牙区牙列的编码对法医学同一认定均具有较高的价值，而前牙区虽有一定的法医学同一认定价值，但其识别率不高。

Objective All of the the X-ray orthopantomogram were comprehensively observed,sieved the index-es of forensic identification for dentition patterns,it will provide a theoretical basis for the use of X-ray orthopantomo-gram in forensic identification indexes. Methods Eight hundreds samples randomly selected.in this study indexes were selected for dentition patterns according to the characters of dental alignment,dental pathological changes and intervention patterns. Eventually diversity of the indexes would be statisticsed and analysised. Results The group with randomly selected with or without therapy in 600 samples had its diversity in the full dentition patterns、in the maxillary、in the mandible was 90.7%、74.8%、74.3%.The diversity in the right maxillary、in the left maxillary、in the right mandible、in the left mandible was 68.8%、69.3%、63.7%、66.8%. The diversity in the in anterior regions、in the upper-anterior regions、in the infra-anterior regions was 24.3%、25.7%、17.8%. The group with randomly selected with therapy in 200 samples had its diversity in the full dentition patterns、in the maxillary、in the mandible was 99.0%、98.0%、98.5%.The diversity in the right maxillary、in the left maxillary、in the right mandible、in the left mandible was 96.5%、97.5%、98.5%、97.5%.The diversity in the in anterior regions、in the upper-anterior regions、in the infraanterior regions was 54.0%、51.5%、59.5%. Conclusions The group with dental interventions had very good full dentition di-versity in full dentition involved the posterior regions.The diversity in the anterior regions was so low that did not to u-tilize the forensic identification.
