The purpose of this study is to estimate chronological age and determine whether individuals were aged under or over 18 years using root pulp visibility (RPV) in cone-beam computed tomography (CBCT) images. The study included CBCT images of 699 individuals aged between 15 and 75 years. One thousand twenty-three mandibular second molar (2M) teeth were evaluated using Olze's RPV method in four stages. Descriptive statistics of the stages and the relationship between the stages and the chronological age were assessed. The distribution of the stages was analyzed according to the 18-year age threshold. There was a positive correlation between RPV stages and chronological ages in both sexes. For females and males, the mean ages of stage 0, stage 1, and stage 2, for females and males, were found as 27.21, 28.93, and 33.68 years, and 37.69, 40.9, and 44.88 years, respectively. Stage 0 and stage 1 were found both in individuals aged under and over 18 years, and stage 2 and stage 3 were not observed in individuals aged under 18 years. The presence of stage 2 and stage 3 may be an indication that an individual is aged over 18 years according to Olze's RPV age estimation method. For more reliable results, 2M teeth should be examined bilaterally in forensic science.
本研究的目的是利用锥形束计算机断层扫描（CBCT）图像中的牙髓可见度（RPV）来估计实足年龄，并确定个体年龄是否在18岁以下或以上。该研究纳入了699名年龄在15至75岁之间个体的CBCT图像。使用Olze的RPV方法分四个阶段对123颗下颌第二磨牙（2M）进行了评估。评估了各阶段的描述性统计数据以及各阶段与实足年龄之间的关系。根据18岁的年龄阈值分析了各阶段的分布情况。男女的RPV阶段与实足年龄之间均呈正相关。对于女性和男性，0期、1期和2期的平均年龄分别为27.21岁、28.93岁和33.68岁，以及37.69岁、40.9岁和44.88岁。18岁以下和18岁以上的个体中均发现了0期和1期，18岁以下的个体中未观察到2期和3期。根据Olze的RPV年龄估计方法，2期和3期的存在可能表明个体年龄超过18岁。为获得更可靠的结果，在法医学中应对双侧的2M牙齿进行检查。
