The purpose of the present study was to establish the distribution of need for treatment of dental caries and also to evaluate the changes in the distribution of DMFT scores in cohorts of schoolchildren aged 7-15 yr. There was a decrease in the proportion of children with high DMFT scores during the study period. The difference was most pronounced at the age of 13 yr. Polarization of the DMFT scores was most obvious at 10 yr, but was also seen at 13 yr. The proportion of patients at risk of caries differs from one age group to another.
本研究的目的是确定龋齿治疗需求的分布情况，并评估7至15岁学龄儿童队列中DMFT评分分布的变化。在研究期间，DMFT评分高的儿童比例有所下降。这种差异在13岁时最为明显。DMFT评分的两极分化在10岁时最为明显，但在13岁时也有体现。龋齿风险患者的比例在不同年龄组之间存在差异。
