: In this study, we aimed to evaluate the accuracy of four radiological methods for dental age estimation and to test which method is the most reliable in Montenegrin children. : To determine dental age, we examined 351 panoramic radiographs of 190 female and 161 male children between the ages of 6 and 12 using the Demirjian method, Willems method, the European formula, and the BAF. The estimated dental age was compared with the chronological age, and the average, absolute, and standard deviations were calculated. : When comparing dental age to chronological age in females, overestimation occurred when using the Demirjian and Willems methods, whereas the European formula and the BAF resulted in underestimations. Only the European formula underestimated dental age in males, while the other three methods caused overestimations in comparison to chronological age. The European formula and the BAF revealed that, when all age groups were included, approximately 57.1-61% of patients deviated from their chronological age by less than six months. When using Demirjian's method, nearly 30-35% of patients had dental ages that were either overestimated or underestimated by more than a year. : The most accurate method for estimating the dental age of children under 13 in the Montenegrin population is the European formula. The Demirjian method had the lowest accuracy, whereas that in the BAF and the Willems method was similar.
在本研究中，我们旨在评估四种放射学方法用于估计牙龄的准确性，并测试哪种方法在黑山儿童中最可靠。为了确定牙龄，我们使用德米尔坚方法、威廉姆斯方法、欧洲公式和BAF，对190名6至12岁女童和161名6至12岁男童的351张全景X线片进行了检查。将估计的牙龄与实际年龄进行比较，并计算平均值、绝对偏差和标准差。在女性中，将牙龄与实际年龄进行比较时，使用德米尔坚方法和威廉姆斯方法会出现高估，而欧洲公式和BAF则导致低估。在男性中，只有欧洲公式低估了牙龄，而其他三种方法与实际年龄相比导致高估。欧洲公式和BAF显示，当纳入所有年龄组时，约57.1%-61%的患者与实际年龄的偏差小于6个月。使用德米尔坚方法时，近30%-35%的患者牙龄被高估或低估超过1年。在黑山人群中，估计13岁以下儿童牙龄最准确的方法是欧洲公式。德米尔坚方法的准确性最低，而BAF和威廉姆斯方法的准确性相似。
