The present study analysed the development of caries in 653 first permanent molars annually over a period of 5 years in children who were 7 years-old at baseline. The cumulative caries experience increased from 6.0% at baseline to 35.2% at the end of the study period. There were no appreciable differences in the annual incremental rate of caries experience among males and females. At baseline, the Malays and Indians have the highest and lowest caries experience respectively. At 12 years of age, the Chinese have the highest caries experience whilst the data for the Malays and Indians were comparable. The highest cumulative percentage increase in caries experience for the Malays, Chinese and Indians were between the ages of 7 to 8, 9 to 10 and 8 to 9 respectively while the average annual caries increment were 4.5%, 7.3% and 5.0% respectively.
本研究分析了653颗第一恒磨牙的龋病发展情况，这些牙齿来自基线年龄为7岁的儿童，研究为期5年，每年进行一次检查。龋病累积患病率从基线时的6.0%上升至研究期末的35.2%。男性和女性在龋病患病率的年增长率上没有明显差异。基线时，马来族和印度族儿童的龋病患病率分别最高和最低。12岁时，华裔儿童的龋病患病率最高，而马来族和印度族儿童的数据相近。马来族、华裔和印度族儿童龋病患病率累积增幅最高的年龄段分别为7至8岁、9至10岁和8至9岁，平均年龋病增长率分别为4.5%、7.3%和5.0%。
