The importance of age estimation in the forensic field is inherent to the process of establishing the biological profile of children, sub-adults and adults. The established profile might be useful for the identification of deceased victims or living individuals when it comes to age of legal interest. In parallel, age estimation is also investigated for clinical purposes, especially for the diagnosis of dental and bone maturation. Several studies were developed to provide accurate age estimation methods based on skeletal and dental development. This study aimed to apply and compare Cameriere's and Willems' methods for dental age estimation in a Brazilian sample. Two examiners performed image analysis and method application in 180 panoramic radiographs of Brazilian children aged 6-14 years old. The ages estimated with both methods revealed a good correlation with the chronological ages of Brazilian boys and girls. Cameriere's method showed a slight underestimation of 0.05 years for girls and 0.03 for boys. Willems' method, on the other hand, showed an overestimation of -0.47 years for girls and -0.39 for boys. Better age estimates were obtained combining the outcomes of both methods. In practice, Cameriere's and Willems' methods reached reliable outcomes and could be applied for dental age estimation purposes.
年龄估测在法医学领域的重要性，源自于建立儿童、青少年和成年人的生物学特征。该既定特征可能有助于识别有法律利益的死亡受害者或活体个人的年龄。同时，年龄估测也出于临床目的进行研究，特别是用于牙和骨成熟度的诊断。已经开展了多项研究，旨在提供基于骨骼和牙齿发育的准确年龄估测方法。本研究旨在将卡米雷利（Cameriere）和威勒姆斯（Willems）的方法应用于巴西人群，并进行比较。两名检查者在 180 名 6-14 岁巴西儿童的全景片上进行了图像分析和方法应用。两种方法估算的年龄与巴西男女的实际年龄具有良好的相关性。卡米雷利（Cameriere）方法显示出女孩轻微低估 0.05 岁，男孩低估 0.03 岁。另一方面，威勒姆斯（Willems）方法显示女孩高估 0.47 岁，男孩高估 0.39 岁。将两种方法的结果结合起来，可以获得更好的年龄估计值。在实际操作中，卡米雷利（Cameriere）和威勒姆斯（Willems）的方法都能得出可靠的结果，可用于牙齿年龄估测。
