提出了一种用于估计牙齿成熟度的更新系统。它扩展了原始系统（Demirjian等人，1973）通过包括2个额外阶段并通过将标准化样本扩大到包括2407名男孩和2349名女孩，基于7颗牙齿的X线照片。2.5-17.0岁男孩和女孩的百分位标准分别列出。评分系统和百分位数标准，提出了2个不同的4个牙齿和比较所有3个系统。这些系统可以测量牙齿成熟度的不同方面。
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 2 extra stages and by enlarging the standardizing sample to include 2407 boys and 2349 girls. Percentile standards from ages 2.5-17.0 yr are presented separately for boys and girls. Scoring systems and percentile standards are presented for 2 different sets of 4 teeth and a comparison of all 3 systems is made. These systems may measure somewhat different aspects of dental maturity.
