AIM
To compare the uniqueness of human dentition in both orthodontically treated and untreated populations and evaluate the reliability of bitemark analysis.
MATERIALS AND METHODS
A total of 1464 maxillary and mandibular casts were fabricated from orthodontically treated and nontreated population. After careful examination of the study teeth, 326 nontreated maxillary cast (Group 1), 333 nontreated mandibular cast (Group 2), 336 orthodontically treated maxillary cast (Group 3), and 320 orthodontically treated mandibular casts (Group 4) were selected for the analysis. For uniformity, the sample size of 320 was selected from each group for comparison.
RESULTS
The arch width was a major cause of variance. In Group 1, only 6.87% of similarity rate was seen, whereas in Group 3, the match rate increased to 55% showing similarity. In Group 2, only 1.87% similarity and Group 4 showed 42.7% match rate.
CONCLUSION
The human dentition may be unique, but it loses its uniqueness once any dental treatment is carried out.
目的
比较正畸治疗人群和未治疗人群中人类牙列的独特性，并评估咬痕分析的可靠性。
材料与方法
从正畸治疗人群和未治疗人群中制作了总共1464个上颌和下颌模型。在仔细检查研究牙齿后，选择326个未治疗的上颌模型（第1组）、333个未治疗的下颌模型（第2组）、336个正畸治疗后的上颌模型（第3组）和320个正畸治疗后的下颌模型（第4组）进行分析。为保持一致性，每组选取320个样本进行比较。
结果
牙弓宽度是差异的主要原因。在第1组中，相似率仅为6.87%，而在第3组中，匹配率提高到55%，显示出相似性。在第2组中，相似性仅为1.87%，第4组的匹配率为42.7%。
结论
人类牙列可能是独特的，但一旦进行任何牙科治疗，它就会失去其独特性。
