This study was designed to establish a Reference Data Set for Dental Age Estimation of young Kuwaiti subjects.
Dental Panoramic Tomographs of 1393 Kuwaiti children, adolescents, and young adults aged between 3 and 26 years were re-used to establish a Reference Data Set. The Tooth Development Stages described by Demirjian et al. in 1973 was used to assess all the teeth on the left side of the Maxilla and the Mandible. The Accuracy and Precision of Dental Age Estimation for Kuwaiti children and adolescents was investigated by calculating the age of children using 50 females and 50 males of known age separate from the main study sample. This was the Validation Sample. Summary data for the individual Tooth Development Stages, comprising the number, mean, and standard deviation were used to estimate the age of the subjects in the Validation Sample using the Simple Average Method to calculate the Dental Age.
There was no statistically significant difference between the Chronological Age and the Dental Age in males with a mean difference of 0.14 years (1.75 months). The difference in females was significant at -0.33 years (-4.1 months).
These data demonstrate that estimated Dental Age in Kuwaiti females is close, just over 4 months, and is very close, in males within 1.75 months of the Chronologic Age.
本研究旨在建立科威特年轻人群的牙齿年龄参考数据集。
重新使用 1393 名科威特儿童、青少年和年轻成年人的全景牙科断层扫描图像，建立参考数据集。使用 Demirjian 等人在 1973 年描述的牙齿发育阶段来评估上颌骨和下颌骨左侧所有牙齿。通过使用来自主要研究样本的 50 名男性和 50 名女性的已知年龄的儿童来计算儿童的年龄，来研究对科威特儿童和青少年的牙齿年龄估计的准确性和精密度。这是验证样本。使用简单平均法计算验证样本中受试者的年龄，使用个体牙齿发育阶段的汇总数据，包括数量、平均值和标准差。
在男性中，年龄的差异没有统计学意义，平均差异为 0.14 岁（1.75 个月）。在女性中，差异具有统计学意义，为-0.33 岁（-4.1 个月）。
这些数据表明，科威特女性的估计牙齿年龄接近 4 个月多一点，男性的牙齿年龄与实际年龄相差 1.75 个月左右。
