The aim of this study was to assess the dental age in Saudi children aged 8.5 to 17 years using the Demirjian method.
Four hundred ninety panoramic radiographs of boys and girls were reviewed retrospectively. All children were placed in the age group closest to their chronological age. The dental age was scored on all seven left mandibular teeth by one examiner.
Both boys and girls in age groups nine to 14 years showed advanced dental age compared to their chronological age which was found to be statistically significant except in age groups nine and 13 years. Saudi boys were 0.3 years and Saudi girls 0.4 years ahead, on average, of French-Canadian children as analyzed by the Demirjian method.
The standard values for French-Canadian children provided by Demirjian vary slightly for application to Saudi children. As a result, new graphs and tables were produced to convert these maturity scores, calculated by the Demirjian method, to the dental age for Saudi children.
本研究旨在使用德米尔坚方法评估8.5至17岁沙特儿童的牙齿年龄。
回顾性分析了490张男孩和女孩的全景X线片。所有儿童均按其实际年龄归入最接近的年龄组。由一名检查者对左侧下颌的七颗牙齿进行牙齿年龄评分。
9至14岁年龄组的男孩和女孩的牙齿年龄均比其实际年龄超前，这在统计学上具有显著意义，但9岁和13岁年龄组除外。通过德米尔坚方法分析，沙特男孩平均比法裔加拿大儿童超前0.3岁，沙特女孩超前0.4岁。
德米尔坚提供的法裔加拿大儿童的标准值在应用于沙特儿童时略有不同。因此，制作了新的图表，将通过德米尔坚方法计算出的这些成熟度评分转换为沙特儿童的牙齿年龄。
