The carious status of the first permanent molar (FPM) was studied in 432 school children (aged 9-12 years) from a randomly selected primary schools from Sharfia area of Jeddah, Kingdom of Saudi Arabia. The sample consisted of 108 children from each age group of 9, 10, 11, and 12 years old. In total, 24.5% had all of their FPMs sound and 6% had all FPMs carious. The prevalence of four sound FPMs varied according to age with the highest (33%) amongst the nine-year olds and the lowest (16.5%) in the oldest children (12 years). Almost one-third (32.5%) of the children, who knew the age of eruption of the FPMs, had all of their molars sound. The children who had received advice regarding oral hygiene from a dentist or parent had more sound FPMs compared to the children who did not receive any advice. The number of carious FPMs increased with age. The prevalence of caries of the FPM was high and increased with increasing age. The level of knowledge had a positive correlation with the caries levels amongst this cohort of scholars.
对来自沙特阿拉伯王国吉达沙尔菲耶地区一所随机选取的小学的432名学童（9至12岁）的第一恒磨牙（FPM）龋病状况进行了研究。样本由9岁、10岁、11岁和12岁每个年龄组的108名儿童组成。总体而言，24.5%的儿童所有第一恒磨牙完好，6%的儿童所有第一恒磨牙龋坏。四颗完好第一恒磨牙的患病率随年龄而异，9岁儿童中患病率最高（33%），年龄最大的儿童（12岁）中患病率最低（16.5%）。几乎三分之一（32.5%）知道第一恒磨牙萌出年龄的儿童所有磨牙完好。与未接受任何口腔卫生建议的儿童相比，接受过牙医或家长口腔卫生建议的儿童有更多完好的第一恒磨牙。龋坏的第一恒磨牙数量随年龄增加。第一恒磨牙的龋病患病率很高，且随年龄增长而增加。在这群学者中，知识水平与龋病水平呈正相关。
