Since dental age estimation methods' accuracy and reliability levels differ in each society, the method should be appropriate for societies. This study aims to evaluate the applicability of Nolla, Willems, and Cameriere methods to Turkish children in the Central Black Sea Region.
This study was conducted based on the panoramic radiographs of 400 children between the ages of 6-14 years admitted to Tokat Gaziosmanpaşa University Faculty of Dentistry, Department of Pediatric Dentistry for examination between 2016 and 2020. Nolla, Willems, and Cameriere methods estimated dental age on the selected panoramic radiographs. While 14 teeth in the left mandible and maxilla were evaluated for Nolla method, seven teeth in the left mandible were evaluated for Willems and Cameriere methods. Data were analyzed using IBM SPSS V23. The Pearson correlation coefficient was used to analyze the relationship between the chronological age (CA) and dental age (DA), and the paired sample t-test was used to analyze the difference.
A statistically significant difference was found between CA-Nolla dental age (p = 0.002), CA-Willems dental age (p < 0.001), and CA-Cameriere dental age (p = 0.033) in boys. The mean differences between dental age and chronological age in boys were -0.24 years in the Nolla method, +0.49 years in Willems method, and -0.17 years in the Cameriere method. A statistically significant difference was found between CA-Nolla dental age (p = 0.001) and CA-Willems dental age (p < 0.001) in girls. The mean differences between dental age and chronological age in girls were -0.27 years in the Nolla method, +0.76 years in the Willems method, and -0.1 years in the Cameriere method.
In this study method providing closest estimation for chronological age among children aged 6-14.99 that were examined in Central Black Sea Region, was the Cameriere method in both girls (79.9%) and boys (80.6%), followed by Nolla method and Willems method, respectively.
由于不同社会的牙科年龄估测方法的准确性和可靠性水平不同，因此该方法应适合于特定社会。本研究旨在评估 Nolla、Willems 和 Cameriere 方法在土耳其中北部黑海地区的适用性。
本研究基于 2016 年至 2020 年间在陶塔夫加济安泰普大学牙科学院儿科牙科就诊的 400 名 6-14 岁儿童的全景 X 光片进行。在选择的全景 X 光片中，使用 Nolla、Willems 和 Cameriere 方法估计牙龄。对于 Nolla 方法，评估了左下颌骨和上颌骨的 14 颗牙齿，对于 Willems 和 Cameriere 方法，评估了左下颌骨的 7 颗牙齿。使用 IBM SPSS V23 分析数据。使用 Pearson 相关系数分析了实际年龄（CA）与牙龄（DA）之间的关系，并使用配对样本 t 检验分析了差异。
在男孩中，CA-Nolla 牙龄（p=0.002）、CA-Willems 牙龄（p<0.001）和 CA-Cameriere 牙龄（p=0.033）之间存在统计学差异。男孩中 Nolla 方法的牙龄与实际年龄之间的平均差异为-0.24 岁，Willems 方法为+0.49 岁，Cameriere 方法为-0.17 岁。在女孩中，CA-Nolla 牙龄（p=0.001）和 CA-Willems 牙龄（p<0.001）之间存在统计学差异。女孩中 Nolla 方法的牙龄与实际年龄之间的平均差异为-0.27 岁，Willems 方法为+0.76 岁，Cameriere 方法为-0.1 岁。
在本研究中，在中北部黑海地区接受检查的 6-14.99 岁儿童中，最接近实际年龄的方法是 Cameriere 方法（女孩为 79.9%，男孩为 80.6%），其次是 Nolla 方法和 Willems 方法。
