摘要

成年人的牙齿年龄估计是法医牙科学中一项具有挑战性的程序。自上世纪 90 年代以来,X 射线照相技术已经能够对成年人进行非侵入性的年龄估计。Kvaal 基于次生牙本质沉积的方法已在多个人群中得到广泛应用。然而,在南美洲,使用这种方法进行的针对特定人群的研究却很少。本研究在巴西成年人的 X 光片样本中测试了 Kvaal 方法的有效性。样本包括 192 张根尖周 X 光片,其中 106 名女性(55.2%)和 86 名男性(44.8%)的年龄在 20 至 80 岁之间。根据 Kvaal 方法评估了上颌右侧(84 人,占 43.8%)和左侧(108 人,占 56.2%)永久中切牙。估计年龄(EA)与年代年龄(CA)之间的林氏一致系数为 0.800(IC95% = 0.753; 0.847)(P < 0.001)。EA 与 CA 之间的平均年龄差为 - 2.84 岁(p < 0.001)。就女性和男性而言,EA 和 CA 之间的平均差异分别为 - 3.82 年 (CI95% = - 5.38; - 2.25) (p < 0.001) 和 - 1.86 年 (CI95% = - 3.56; - 0.17) (p = 0.031)。低估是主要现象,并随着时间的推移而增加。在最初发表 28 年后的今天,Kvaal 的方法对于成人非侵入性牙齿年龄估计仍然是可靠的,尤其是在分析巴西人的上颌恒中切牙时。

Kvaal’s dental age estimation method applied to Brazilian adults—a cross-sectional test of validity
Dental age estimation of adults is a challenging procedure in forensic odontology. Radiographic techniques have enabled non-invasive age estimation of adults since the 90’s. Kvaal’s method based on the deposition of secondary dentin has demonstrated broad applicability in several populations. Population-specific studies with this method, however, are scarce in South America. This study tested the validity of Kvaal’s method in a sample of radiographs of Brazilian adults. The sample consisted of 192 periapical radiographs of 106 females (55.2%) and 86 males (44.8%) with ages between 20 and 80 years old. The permanent maxillary right (n = 84, 43.8%) and left (n = 108, 56.2%) central incisors were assessed based on Kvaal’s method. Lin’s coefficient of concordance between estimated (EA) and chronological (CA) ages was 0.800 (IC95% = 0.753; 0.847) (p < 0.001). The mean difference between EA and CA was − 2.84 years (p < 0.001). For females and males, separately, the mean differences between EA and CA were − 3.82 years (CI95% = − 5.38; − 2.25) (p < 0.001) and − 1.86 years (CI95% = − 3.56; − 0.17) (p = 0.031), respectively. Underestimations were predominant and increased with time. After 28 years of the original publication, Kvaal’s method remains reliable for non-invasive dental age estimation of adults, especially for the analysis of the permanent maxillary central incisors of Brazilian individuals.
