To assess the caries prevalence in 3- to 5-year-old children and determine whether urbanisation and income are associated with the dental decay status of these preschool children residing in the district of Lahore, Pakistan.
Multistage random sampling was done to collect the sample of children from urban and rural areas. A list of children 3 to 5 years of age was prepared, and every 2nd child on the list was randomly selected until a total of 700 children were enrolled in the study. Lady Health Workers (LHWs) were trained to conduct this survey after permission from the pertinent authorities. The data of the children and their mothers regarding their age, gender, socioeconomic status (SES) and area of residence were collected. The caries status of children was recorded using the dmft index as per WHO criteria.
The prevalence of dental caries in preschool children of Lahore was found to be 40.5%. Within this group, caries prevalence was 33.3% in 3-year-old children, 47.6% in 4-year-old children and 75% in the 5-year-old children. The mean dmft score for the entire child population was 1.85 ± 3.26. A significant association was found between caries prevalence, low socioeconomic status, female gender and rural residence.
Preschool children in Lahore, Pakistan have average dmft scores of 1.85 (± 3.26), which are mostly related to untreated carious lesions. Lower caries experience was found to be associated with rural residence and low family income.
评估3至5岁儿童的龋齿患病率，并确定城市化和收入是否与居住在巴基斯坦拉合尔地区的这些学龄前儿童的龋齿状况相关。
采用多阶段随机抽样从城市和农村地区收集儿童样本。编制了一份3至5岁儿童的名单，从名单上每隔一个孩子随机选取，直到共有700名儿童纳入研究。在获得相关当局许可后，对女卫生工作者（LHWs）进行了培训以开展此项调查。收集了儿童及其母亲关于年龄、性别、社会经济地位（SES）和居住地区的数据。根据世界卫生组织标准，使用dmft指数记录儿童的龋齿状况。
拉合尔学龄前儿童的龋齿患病率为40.5%。在这个群体中，3岁儿童的龋齿患病率为33.3%，4岁儿童为47.6%，5岁儿童为75%。所有儿童的平均dmft评分为1.85±3.26。发现龋齿患病率、低社会经济地位、女性性别和农村居住之间存在显著关联。
巴基斯坦拉合尔的学龄前儿童平均dmft评分为1.85（±3.26），这主要与未治疗的龋损有关。发现较低的龋齿发病率与农村居住和低家庭收入有关。
