The quantification of dental caries is usually done by DMFT index but efforts are being made to find an alternative. Caries Assessment Spectrum and Treatment (CAST) is a recent, innovative caries assessment tool which can be used in epidemiological surveys.
To assess dental caries using CAST index among 11-14-year-old school children in Rohtak city, Haryana, India.
A cross-sectional study was carried out among 11-14-year-old children in schools of Rohtak City using multi stage cluster sampling technique. Rohtak city was divided in to nine clusters. In the 2nd stage, one school was randomly selected from each cluster with lottery method. Finally from each selected school, every odd roll number child between age group 11-14 years, were enrolled to reach a sample of 586. Caries was recorded using the CAST index. Each child was clinically examined by a trained examiner using CAST index. Descriptive and inferential statistics were done and Chi-square test was used to find association between caries prevalence and gender. Mann-Whitney U test was used to find any difference of mean DMFT between different age groups.
A total of 586 children were examined. Prevalence of dental caries was 28.6%. Highest caries was observed in lower right first molar and lower left first molar (13.8% and 11.6%) respectively. Pulpal involvement in lower molars was found more than the upper molars.
CAST index presents a simple hierarchical structure of caries spectrum and is a promising index for epidemiological studies with complex quantifiability.
龋齿的量化通常通过DMFT指数进行，但人们正在努力寻找替代方法。龋病评估光谱与治疗（CAST）是一种最新的创新性龋病评估工具，可用于流行病学调查。
在印度哈里亚纳邦罗塔克市11至14岁的在校儿童中，使用CAST指数评估龋齿情况。
采用多阶段整群抽样技术，对罗塔克市学校中11至14岁的儿童进行横断面研究。罗塔克市被划分为九个群组。在第二阶段，通过抽签法从每个群组中随机选取一所学校。最后，从每所选定的学校中，选取年龄在11至14岁之间的每个奇数学号的儿童，以达到586名的样本量。使用CAST指数记录龋齿情况。由一名经过培训的检查人员使用CAST指数对每个儿童进行临床检查。进行描述性和推断性统计，并使用卡方检验来确定龋齿患病率与性别的关联。使用曼-惠特尼U检验来查找不同年龄组之间平均DMFT的差异。
共检查了586名儿童。龋齿患病率为28.6%。右下第一磨牙和左下第一磨牙的龋齿发生率最高，分别为13.8%和11.6%。发现下颌磨牙的牙髓受累情况比上颌磨牙更多。
CAST指数呈现出一种简单的龋齿光谱层次结构，对于具有复杂可量化性的流行病学研究而言，是一个很有前景的指数。
