Abstract

The reduction of the pulpal space following the deposition of secondary dentin is a radiographically visible morphological feature associated with aging. Currently, there is no reference morphological sample for the Northern Brazilian population when it comes to the radiographically visible dental features for age estimation. This study aimed to test an existing method for age estimation based on the canine pulp/tooth area (PTA) ratio and develop a population-specific equation. The sample consisted of 100 peri-apical radiographs of Brazilian males (n = 46) and females (n = 54) from the Northern geographic region. The age of the sampled participants was between 18 and 72 years (mean age = 45.43 ± 14.39 years). The estimated age was obtained with the Cameriere's method. A statistically significant negative (r = −0.595) association was observed between the permanent canine PTA and the chronological age (P = 0.0001). A population-specific equation was structured with a 4-fold (75% × 25%) cross-validation, leading to a mean absolute error of 9.59 years, and root mean square error of 11.66 years (r² = 0.363). This study provided evidence to support the use of Cameriere's pulp/tooth area ratio for the radiographic dental age estimation of Northern Brazilian adults, especially adjusted with a population-specific equation.

利用放射线牙髓/牙齿面积比估算成年人的牙齿形态年龄

继发性牙本质沉积后牙髓间隙的缩小是与衰老相关的放射学可见形态特征。目前，巴西北部人口还没有可用于年龄估计的放射学可见牙齿特征的参考形态样本。本研究旨在测试现有的基于牙髓/牙齿面积（PTA）比值的年龄估算方法，并建立一个针对特定人群的方程。样本包括来自北部地区的巴西男性（n = 46）和女性（n = 54）的 100 张根尖周射线照片。样本参与者的年龄在 18 至 72 岁之间（平均年龄为 45.43 ± 14.39 岁）。估计年龄是用卡默里尔法得出的。从统计学角度看，犬永久性 PTA 与实际年龄之间存在明显的负相关（r = -0.595）（P = 0.0001）。通过 4 倍（75% × 25%）交叉验证构建了一个特定人群方程，得出平均绝对误差为 9.59 岁，均方根误差为 11.66 岁（r2 = 0.363）。这项研究提供了证据，支持使用卡梅里尔的牙髓/牙齿面积比值来估算巴西北部成年人的放射学牙科年龄，特别是使用特定人群方程进行调整。

期刊介绍： Morphologie est une revue universitaire avec une ouverture médicale qui sa adresse aux enseignants, aux étudiants, aux chercheurs et aux cliniciens en anatomie et en morphologie. Vous y trouverez les développements les plus actuels de votre spécialité, en France comme a international. Le objectif de Morphologie est d?offrir des lectures privilégiées sous forme de revues générales, d?articles originaux, de mises au point didactiques et de revues de la littérature, qui permettront notamment aux enseignants de optimiser leurs cours et aux spécialistes d?enrichir leurs connaissances.
