Based on the previous national oral health survey in India, some variation was observed in oral health status and behavior between the urban and rural population. Thus, the present study aimed to assess the dental caries experience in deciduous dentition of 6-year-old urban and rural schoolchildren of Udaipur district and to evaluate the influence of socio behavioral characteristics on dental caries experience.
A combination of multi stage and cluster sampling procedure was executed to collect a representative sample of 875, 6-year-old school children. Clinical examination for caries was conducted using dmft (decayed, missing and filled teeth) index. Socio - demographic information was collected prior to clinical examination in addition to information on oral health behavior by personal interviews.
Only 7.8% children reported of brushing their teeth twice or more than twice daily. Rural children visited the dentist less often than the urban children (P < 0.05). Greater proportion of boys (62.2%) experienced caries than girls (55.1%), decayed component constituted a major contribution for dmft. Multivariate analysis demonstrated the influence of gender, urbanization, tooth brushing frequency, dental visits, parent's education and occupation on caries occurrence.
Rural children and boys experienced greater caries than their urban and girl counterparts. Caries experience was related to the parent's occupation and education. Moreover, caries occurrence was influenced by brushing frequency and dental visiting habits.
基于此前印度全国口腔健康调查，城乡人口的口腔健康状况和行为存在一些差异。因此，本研究旨在评估乌代布尔地区6岁城乡学童乳牙列的龋病经历，并评估社会行为特征对龋病经历的影响。
采用多阶段整群抽样程序，收集了875名6岁学童的代表性样本。使用dmft（龋、失、补牙）指数进行龋病临床检查。除通过个人访谈收集口腔健康行为信息外，在临床检查前还收集了社会人口学信息。
只有7.8%的儿童报告每天刷牙两次或两次以上。农村儿童看牙医的频率低于城市儿童（P<0.05）。患龋男孩的比例（62.2%）高于女孩（55.1%），龋坏部分在dmft中占主要部分。多变量分析表明性别、城市化、刷牙频率、看牙医次数、父母教育程度和职业对龋病发生有影响。
农村儿童和男孩比城市儿童和女孩患龋更多。龋病经历与父母的职业和教育程度有关。此外，龋病的发生受刷牙频率和看牙医习惯的影响。
