Dental caries is a major, multifactorial oral condition that causes the demineralization of tooth enamel and impacts approximately half of the world's child population. This study aimed to determine the prevalence of dental caries among school-going children aged 7 to 13 years in Kabul city.
This descriptive cross-sectional study was conducted with 491 students aged 7 to 13 years in Kabul during the first half of 2019. A multistage cluster sampling method was used, in which educational zones, schools, and classes were selected. The data were collected using pre-structured questionnaires through face-to-face interviews and oral examinations of students using dental probes and mouth mirrors while adhering to infection control protocols. The collected data were analyzed using Statistical Package for Social Science version 21.0, and a p-value < 0.005 was considered as statistically significant.
The average age of the study participants was 9.9 ± 1.8 years. Boys made up approximately 45% of the participants, while 54.8% were girls. The overall prevalence of dental caries was 78.8%, with 62.1% in deciduous teeth and 42.8% in permanent teeth. Among students who did not brush their teeth, the prevalence of dental caries was 84.8%, compared to 81.7% for those who brushed once daily, 78.7% for those brushing twice daily, and 67.4% for those brushing three times daily (p = 0.022). About 10% of students had dental calculus, with a prevalence of 17.0% among those aged eleven and older, 10.0% among students aged nine to ten years, and 5.9% among students aged eight and younger (p = 0.006). Poor oral hygiene affected nearly one-third of the students, with 34.2% among boys and 30.9% among girls. Poor oral hygiene was more prevalent in students aged eight and younger (38.8%) compared to those aged eleven and older (25.9%) (p = 0.023).
The prevalence of dental caries among students aged 7 to 13 years in Kabul schools was similar to that in most developing countries. The prevalence of dental calculus was greater among students aged eleven years and older. Over 99% of the students surveyed had not undergone any dental treatment.
龋齿是一种主要的、多因素的口腔疾病，会导致牙釉质脱矿，影响全球约一半的儿童人口。本研究旨在确定喀布尔市 7 至 13 岁上学儿童的龋齿患病率。
这是一项描述性的横断面研究，于 2019 年上半年在喀布尔的 491 名 7 至 13 岁的学生中进行。采用多阶段聚类抽样方法，选择教育区、学校和班级。使用预结构化问卷通过面对面访谈收集数据，并使用牙探针和口腔镜对学生进行口腔检查，同时遵守感染控制协议。使用统计软件包 21.0 分析收集的数据，p 值<0.005 被认为具有统计学意义。
研究参与者的平均年龄为 9.9±1.8 岁。男生约占参与者的 45%，而女生占 54.8%。龋齿的总体患病率为 78.8%，其中乳牙为 62.1%，恒牙为 42.8%。未刷牙的学生中，龋齿的患病率为 84.8%，而每天刷牙一次的学生为 81.7%，每天刷牙两次的学生为 78.7%，每天刷牙三次的学生为 67.4%（p=0.022）。约 10%的学生有牙石，11 岁及以上学生的患病率为 17.0%，9 至 10 岁学生为 10.0%，8 岁及以下学生为 5.9%（p=0.006）。近三分之一的学生口腔卫生状况较差，男生为 34.2%，女生为 30.9%。8 岁及以下学生的口腔卫生状况较差（38.8%），而 11 岁及以上学生的口腔卫生状况较差（25.9%）（p=0.023）。
喀布尔学校 7 至 13 岁学生的龋齿患病率与大多数发展中国家相似。牙石的患病率在 11 岁及以上的学生中较高。接受过任何牙科治疗的学生不足 1%。
