One of the most interesting reasons for needing to estimate age in adult subjects is to ascertain the age of a person of questionable pensionable age. This problem is becoming increasingly important in Europe, owing to the high number of immigrants without valid birth certificates. The aim of this paper is to evaluate the application of the apposition of secondary dentine of canines by the method of Cameriere et al. [10], in order to estimate the pensionable age of subjects without proper birth certificates. Periapical X-rays of 180 canines from 90 subjects aged between 50 and 79, 46 men and 44 women, were analysed. Estimated ages were used to test the medico-legal question as to whether an individual was older or younger than 65 years of age. In subjects under 65, age was correctly evaluated in 91% and 89% of individuals using maxillary and mandibular canines, respectively. In subjects over 65, of pensionable age, estimates were correct in 85% and 88% of cases, respectively. The proportion of individuals with correct classifications was 89% for both maxillary and mandibular canines taken together. In only four subjects, the results of maxillary and mandibular canines were discordant; in the other 86 subjects, the test of maxillary and mandibular canines yielded concordant results. Among the latter, the proportion of individuals who were really aged 65 years or older, and who were correctly estimated as such, was 94%, and the proportion of individuals younger than 65 years of age who were correctly estimated as such was 96%.
需要估算成年人年龄的最有趣原因之一是确定有疑问的领养老金年龄的人的年龄。由于没有有效出生证明的移民人数众多，这个问题在欧洲变得越来越重要。本文旨在评估 Cameriere 等人 [10] 提出的犬齿次生牙本质附加方法在估算没有适当出生证明的受试者的养老金年龄方面的应用。分析了 90 名年龄在 50 至 79 岁之间的受试者的 180 颗犬齿的根尖 X 光片，其中 46 名男性和 44 名女性。估计年龄用于检验个体是否超过 65 岁的医学法律问题。在 65 岁以下的受试者中，上颌和下颌犬齿分别正确评估了 91%和 89%的个体的年龄。在 65 岁以上的有资格领取养老金的受试者中，估计值分别在 85%和 88%的病例中正确。上颌和下颌犬齿联合使用时，正确分类的个体比例为 89%。只有 4 名受试者的上颌和下颌犬齿结果不一致；在其他 86 名受试者中，上颌和下颌犬齿的测试结果一致。在后者中，真正年龄为 65 岁或以上且被正确估计为如此的个体比例为 94%，年龄小于 65 岁且被正确估计为如此的个体比例为 96%。
