Severe early childhood caries (sECC) is a public health problem that continues to affect infants and preschool children worldwide. Knowledge of the changes in dental development is important for paediatric dentists in order to determine a treatment plan. The aim of this study was to investigate dental development in children with sECC, compared to age and gender-matched controls, by calculating the dental age (DA).
A total of 300 children (144 females, 156 males) with sECC aged 5 years were studied and compared with 300 control subjects (caries-free), case-matched for gender and age. The dental development was assessed using the DA estimation method of Demirjian et al. [1973], and data were statistically analysed using a 2-sided t test and chi-squared test.
The mean differences between the DA and chronological age (CA) in the sECC females and males were 0.67±0.6 years and 0.98±0.6 years, respectively, whereas the results of the case controls were 1.44±0.8 years for the females and 1.57±0.6 years for the males. The differences between the sECC and case control groups were significant for both genders (p<0.001).
Children with severe early childhood caries have lower rates of dental development when compared to normal children.
严重婴幼儿龋（sECC）是一个全球性的公共卫生问题，继续影响着全球的婴儿和学龄前儿童。了解牙齿发育的变化对于儿科牙医来说很重要，以便确定治疗计划。本研究旨在通过计算牙龄（DA），来研究患有 sECC 的儿童与年龄和性别匹配的对照组儿童的牙齿发育情况。
共研究了 300 名年龄为 5 岁的患有 sECC 的儿童（女性 144 名，男性 156 名），并与 300 名性别和年龄匹配的对照受试者（无龋）进行了比较。使用 Demirjian 等人[1973]的 DA 估计方法评估牙齿发育情况，使用双侧 t 检验和卡方检验对数据进行统计学分析。
sECC 女性和男性的 DA 与实际年龄（CA）之间的平均差异分别为 0.67±0.6 岁和 0.98±0.6 岁，而病例对照的结果分别为女性为 1.44±0.8 岁，男性为 1.57±0.6 岁。sECC 组与病例对照组之间的差异在两种性别中均具有统计学意义（p<0.001）。
与正常儿童相比，患有严重婴幼儿龋的儿童牙齿发育速度较慢。
