The diversity of dental patterns is a fundamental topic in disaster victim identification. The current scientific literature, however, is scarce of data regarding young individuals. This study aimed to assess the radiographic diversity of dental patterns, considering missing, unrestored, and filled teeth in young individuals. The sample consisted of 7219 panoramic radiographs of individuals between 12 and 22.9 years. The permanent teeth, except third molars, were coded as missing, unrestored, or filled and odds ratios (OR) were calculated based on sex, dental arch, and age. The sex-combined sample had 1.116 distinctive dental patterns. "All unrestored" teeth was the most common pattern (OR: 0.437) followed by the sequence of unrestored teeth except restored mandibular first molars (OR: 0.021). Females had more distinctive dental patterns than males (< .001), while males had more unrestored teeth (< .001). In the age category of 12-12.9 years, the OR for finding a distinctive dental pattern was 11%, while in the age category of 22-22.9 years it increased to 58%. On the other hand, the OR for "all unrestored" gradually decreased according to age (74% in the younger category, and 23% in the older age category). The distinctiveness of dental patterns among young individuals is affected by the predominance of unrestored teeth. However, registering a single filled tooth in a remaining unrestored dentition can reduce exponentially the probability of finding an identical pattern of missing, unrestored and filled teeth.
牙齿形态的多样性是灾难遇难者身份识别中的一个基本课题。然而，当前科学文献中关于年轻人的数据稀缺。本研究旨在评估年轻人牙齿形态的影像学多样性，同时考虑缺失牙、未修复牙和已充填牙。样本包括7219张年龄在12至22.9岁之间个体的全景X线片。除第三磨牙外的恒牙被编码为缺失、未修复或已充填，并根据性别、牙弓和年龄计算优势比（OR）。性别合并样本有1.116种独特的牙齿形态。“全未修复”牙齿是最常见的形态（OR：0.437），其次是除下颌第一磨牙已修复外的未修复牙齿序列（OR：0.021）。女性比男性有更多独特的牙齿形态（<0.001），而男性有更多未修复的牙齿（<0.001）。在12至12.9岁年龄组中，发现独特牙齿形态的OR为11%，而在22至22.9岁年龄组中增加到58%。另一方面，“全未修复”的OR随年龄逐渐降低（较年轻组为74%，较年长组为23%）。年轻人牙齿形态的独特性受未修复牙齿占主导的影响。然而，在其余未修复的牙列中记录一颗已充填牙可成倍降低发现缺失、未修复和已充填牙齿相同形态的概率。
