An updated system for estimating dental maturity is presented. It extends the original system (Demirjian et al., 1973) based on radiographs of 7 teeth by including two extra stages, and by enlarging the standardizing sample to include 2407 boys and 2349 girls. Percentile standards from ages 2-5 to 17-0 years are presented separately for boys and girls. Scoring systems and percentile standards are presented for two different sets of 4 teeth and a comparison of all three systems is made. It is suggested that these systems may measure somewhat different aspects of dental maturity.
本文介绍了一种更新的牙齿成熟度评估系统。该系统在基于7颗牙齿X线片的原始系统（Demirjian等人，1973年）基础上进行了扩展，增加了两个额外阶段，并扩大了标准化样本，纳入了2407名男孩和2349名女孩。分别给出了2至5岁到17至0岁男孩和女孩的百分位数标准。针对两组不同的4颗牙齿给出了评分系统和百分位数标准，并对这三种系统进行了比较。研究表明，这些系统可能测量的是牙齿成熟度的不同方面。
