Age is a crucial factor in identifying a person in forensic medicine. Dentition is one of the physiological indicators of chronological age. Radiographic dental age assessment is a simple, noninvasive and reproducible method. Age estimation is also done by evaluating tooth wear. To assess and compare morphological parameters of maxillary central incisors evaluated on radiographs using Kvaal's method with occlusal wear of posterior teeth using Kim's method in age estimation. A total of 50 individuals from 20 to 70 years of both genders were included. Radiographic analysis and occlusal tooth wear were calculated based on Kvaal's method and Kim's scoring criteria, respectively. The mean predicted age of the patient through radiographic analysis by Kvaal's method was 44.762. In contrast, the mean predicted age through occlusal tooth wear analysis of posterior teeth by Kim's scoring system was 44.842. Furthermore, the difference from the population mean age was 0.002 for radiographic analysis by Kvaal's method and 0.081 by occlusal tooth wear analysis by Kim's system. The result infers radiographic analysis by Kvaal's method was more accurate than occlusal tooth wear analysis by Kim's system in age estimation.
年龄是法医学中识别个体的关键因素。牙列是实足年龄的生理指标之一。口腔X光片牙齿年龄评估是一种简单、无创且可重复的方法。年龄估计也可通过评估牙齿磨损来进行。在年龄估计中,使用Kvaal法对上颌中切牙在X光片上评估的形态学参数与使用Kim法对后牙咬合磨损进行评估和比较。总共纳入了50名年龄在20至70岁之间的男女个体。分别基于Kvaal法和Kim评分标准计算口腔X光片分析和咬合牙齿磨损情况。通过Kvaal法进行口腔X光片分析得出的患者平均预测年龄为44.762岁。相比之下,通过Kim评分系统对后牙咬合磨损分析得出的平均预测年龄为44.842岁。此外,Kvaal法进行口腔X光片分析与总体平均年龄的差异为0.002,而Kim系统进行咬合牙齿磨损分析的差异为0.081。结果表明,在年龄估计方面,Kvaal法进行的口腔X光片分析比Kim系统进行的咬合牙齿磨损分析更准确。
