To evaluate the reliability and validity of Demirjian's, Willems, Nolla's, Haavikko's, and Cameriere's radiographic methods of dental-age estimation in a population of Malaysian children.
A total of 426 dental panoramic radiographs of 5-15-year-old Malaysian children were included in the study. The mean age error and absolute age error for all the methods were calculated and their usability analyzed.
The Nolla, Willems. and Demirjian methods overestimated the dental age with a mean of 0.97, 0.54, and 0.54 years, respectively, while the Cameriere and Haavikko methods underestimated by 0.41 and 1.31 years, respectively. The Cameriere method was highly precise and accurate in the population of Malaysian children, whereas the Haavikko and Demirjian methods were the least precise and accurate.
The Cameriere method of dental-age estimation is highly valid and reliable for Malaysian population, followed by the Willems and Nolla methods.
评估德米尔坚法、威廉姆斯法、诺拉法、哈维科法和卡梅里埃雷法在马来西亚儿童群体中进行牙龄估计的放射学方法的可靠性和有效性。
本研究纳入了426张5至15岁马来西亚儿童的口腔全景X线片。计算了所有方法的平均年龄误差和绝对年龄误差，并分析了它们的可用性。
诺拉法、威廉姆斯法和德米尔坚法分别高估牙龄0.97年、0.54年和0.54年，而卡梅里埃雷法和哈维科法分别低估0.41年和1.31年。卡梅里埃雷法在马来西亚儿童群体中高度精确且准确，而哈维科法和德米尔坚法最不精确且准确。
卡梅里埃雷法进行牙龄估计对马来西亚人群高度有效且可靠，其次是威廉姆斯法和诺拉法。
