Age Estimation has been considered as a human basic right, carried out through the use of tables for dental age assessment based on the chronology of tooth eruption. As such, the final aim of this investigation is to create tables with applicability to the Portuguese population, for the different scoring systems used and combined different statistical approaches.
For this purpose, dental age assessment was achieved in all four third molars, using different scoring systems, in a total sample of 626 orthopantomograms (324 females, 302 males), aged between 12 and 25 years old, from the database population of Lisbon North University Hospital Center, approved by the Ethic Committee.
The values of validation showed excellent results both on precision and on reproducibility. Mostly all methods showed statistically significant differences between the estimated age and the chronological age and, therefore, the presence of estimation errors. Kullman's and Mincer's methods are the ones with best applicability in the Portuguese population, in the lower third molars. The reliability measures (sensitivity, specificity and accuracy) values decrease as age increases.
A combination of the scoring systems as a protocol for dental age assessment in Portuguese nationality was established. Tables, for all the scoring systems used, were made with applicability in the Portuguese population.
年龄估测被视为一项人类基本权利，可以通过使用基于牙齿萌出时间的牙齿年龄评估表来实现。因此，这项研究的最终目的是为葡萄牙人群创建适用不同评分系统的表格，并结合不同的统计方法。
为此，我们在里斯本北方大学医院中心数据库人群中，对 626 张全景片（324 名女性，302 名男性）中的四颗第三磨牙进行了不同评分系统的牙齿年龄评估，年龄在 12 至 25 岁之间。该研究方案已获得伦理委员会的批准。
验证结果表明，在精度和可重复性方面均表现出色。大多数方法都显示了估计年龄与实际年龄之间存在统计学显著差异，因此存在估计误差。在葡萄牙人群中，Kullman 和 Mincer 方法在较低的第三磨牙中具有最佳的适用性。可靠性指标（敏感性、特异性和准确性）值随着年龄的增加而降低。
我们建立了一种将评分系统结合起来的协议，用于评估葡萄牙人群的牙齿年龄。我们为所使用的所有评分系统制作了适用于葡萄牙人群的表格。
