Age estimation is important to set an anthropological profile in human remains, as well as in legal issues where the suspect or victim doesn't have documents that prove the real age. The age estimation, in adults, is a challenge, and it can be analyzed through some dental stages. This study aimed to test Olze's method in a Brazilian sample composed by adults, aged between 20 and 70 years old, both sex.
For experiments, 306 orthopantomography from Brazilian individuals between 20 and 70 years were selected. The dental involution through four different dental parameters were classified and the correlation between chronological age and the estimated age was examined by means of a multiple regression analysis.
The results showed that up to 41 years old, the correlation between real age and the interval obtained was considered strongly positive (R = 0.8-1), and the percentage of matching was 78.78% for men and 71.21% for women. From 42 years old up, the correlation between real age and the estimation was considered null (R = 0) for both sex, and the percentage of matching was 17.24% for men and 6.89% for women.
It could be concluded that the method is effective for age estimation up to 41 years old, but has limitations to be used over this age in Brazilian people.
年龄估计对于确定人类遗骸的人类学特征以及在嫌疑人或受害者没有证明其真实年龄文件的法律问题中都很重要。在成年人中进行年龄估计是一项挑战，可以通过一些牙齿发育阶段来分析。本研究旨在在一个由年龄在20至70岁之间的成年男女组成的巴西样本中测试奥尔泽方法。
为进行实验，选取了306例年龄在20至70岁之间的巴西人的口腔全景片。通过四个不同的牙齿参数对牙齿退化进行分类，并通过多元回归分析检查实际年龄与估计年龄之间的相关性。
结果显示，在41岁之前，实际年龄与所得区间之间的相关性被认为是强正相关（R = 0.8 - 1），男性的匹配百分比为78.78%，女性为71.21%。从42岁起，实际年龄与估计值之间的相关性在两性中均被认为是零相关（R = 0），男性的匹配百分比为17.24%，女性为6.89%。
可以得出结论，该方法在41岁之前进行年龄估计是有效的，但在巴西人群中超过这个年龄使用存在局限性。
