Introduction In forensic literature, estimating an individual's age has garnered a lot of attention. With increasing age, the size of the dental pulp cavity shrinks as a result of secondary dentin deposits. This could be used as a measure of age. Aside from morphological approaches, radiological approaches might be used to analyze this regression shift. Kvaal's method calculates the chronological age of individuals based on the age-pulp size relationship on periapical dental radiographs. Purpose This study aims to use Kvaal's method to estimate the chronological age of patients using digital panoramic radiographs and verify the validity of regression equations proposed by Kvaal et al. in the Saudi population. Material and methods A total of 74 digital orthopantomograms were randomly selected from Qassim University Dental Clinic in Saudi Arabia, ranging in age from 18 to 64 years (mean age 32 years). The radiographs were taken between 2018 and 2021 according to inclusion and exclusion criteria. Results When the Kvaal technique was applied to Saudi members, there was no statistically significant discrepancy between the estimated and chronological ages. The coefficient of determination R2 was highest when three mandibular teeth were evaluated together (0.752). Conclusion The most accurate indicator for age assessment was "M" (mean worth, all things considered) and "W L" (contrast among "Width" and "Length").
引言 在法医学文献中,估计个体年龄备受关注。随着年龄增长,由于继发性牙本质沉积,牙髓腔的大小会缩小。这可作为年龄的一种衡量指标。除形态学方法外,放射学方法也可用于分析这种退缩变化。Kvaal方法基于根尖牙片上的年龄与牙髓大小关系计算个体的实际年龄。目的 本研究旨在使用Kvaal方法通过数字化全景牙片估计患者的实际年龄,并验证Kvaal等人提出的回归方程在沙特人群中的有效性。材料与方法 从沙特阿拉伯卡西姆大学牙科诊所随机选取74张数字化曲面断层片,年龄范围为18至64岁(平均年龄32岁)。根据纳入和排除标准,这些牙片于2018年至2021年期间拍摄。结果 当将Kvaal技术应用于沙特人群时,估计年龄与实际年龄之间无统计学显著差异。当一起评估三颗下颌牙齿时,决定系数R2最高(0.752)。结论 年龄评估最准确的指标是“M”(综合考虑的均值)和“W L”(“宽度”与“长度”之间的对比)。
