The large number of extant Dental Panoramic Tomographs of Afro-Trinidadian subjects were collected and Tooth Development Stages (TDSs) were assessed for each of the 878 radiographs to provide a Reference Dataset (RDS) of Afro-Trinidadian children and adolescents. The values for each of the 256 TDSs present were statistically significantly different from the values for the same TDSs in the UK Caucasian RDS. A validation study of 50 radiographs of Afro-Trinidadian subjects from 24 boys and 26 girls were assessed to enable calculation of the Dental Age (DA). The DA calculated using the UK Caucasian RDS was statistically significantly different from the chronological age. The same radiographs were used to calculate the Age of Attainment of the individual Tooth Development Stages for females and males in both the UK Caucasian subjects, and the Afro-Trinidadians. The majority of these comparisons showed the TDSs in Afro-Trinidadian subjects to develop earlier than the UK Caucasian subjects by approximately 8 months.
收集了大量现存的非洲裔特立尼达受试者的牙科全景断层扫描图像，并对878张X光片中的每一张进行了牙齿发育阶段（TDS）评估，以提供非洲裔特立尼达儿童和青少年的参考数据集（RDS）。所呈现的256个TDS中的每一个值与英国白种人RDS中相同TDS的值在统计学上有显著差异。对来自24名男孩和26名女孩的50张非洲裔特立尼达受试者的X光片进行了验证研究，以计算出牙龄（DA）。使用英国白种人RDS计算出的DA与实际年龄在统计学上有显著差异。相同的X光片用于计算英国白种人和非洲裔特立尼达男性和女性个体牙齿发育阶段的达到年龄。这些比较中的大多数表明，非洲裔特立尼达受试者的TDS比英国白种人受试者早约8个月发育。
