The objective of the present study was to investigate the caries experience and patterns in a sample of 6- and 13- year old school children and to estimate the contributing roles of the likely risk indicators.
Data were obtained from 400 (196, 6-year old and 204, 13-year old) school children. A questionnaire was sent to the children parents to measure socioeconomic, socio-demographic, and behavioral variables. Dental caries detection was performed according to the World Health Organization criteria (dmft and DMFT). The mean dmft/DMFT scores were analysed either as a continuous (calculating means and standard deviations) or as a categorical variable (providing proportions). We also created a multivariate logistic regression model.
Overall caries prevalence was dmft > 0 = 26.75% (6-years old = 50.51%; 13-years old = 3.92%) and DMFT > 0 = 25.25% (6-years old = 12.75%; 13-years old = 37.25%). Multivariate analysis showed that presence of enamel defects, low socio-economic status, mothers' educational levels were significantly associated with caries prevalence in both the dentition, and caries in the primary teeth (OR = 4.87) were associated with DMFT > 0. Most commonly affected teeth were lower first molar in permanent dentition and lower second molars in primary dentition. In both the dentition occlusal surfaces were most often affected compared to other surfaces.
This study has identified clinical, socio-economic, and behavioral determinants for dental caries in primary and permanent dentition on Indian schoolchildren. Key words:Dental caries experience, socio-economic status, enamel defects, tooth surface distribution.
本研究的目的是调查6岁和13岁学龄儿童样本中的龋病经历和模式，并评估可能的风险指标的促成作用。
数据来自400名学龄儿童（196名6岁儿童和204名13岁儿童）。向儿童家长发送问卷，以测量社会经济、社会人口统计学和行为变量。根据世界卫生组织标准（dmft和DMFT）进行龋齿检测。将平均dmft/DMFT分数作为连续变量（计算均值和标准差）或分类变量（提供比例）进行分析。我们还创建了一个多变量逻辑回归模型。
总体龋病患病率为dmft>0=26.75%（6岁儿童=50.51%；13岁儿童=3.92%），DMFT>0=25.25%（6岁儿童=12.75%；13岁儿童=37.25%）。多变量分析表明，釉质缺陷的存在、低社会经济地位、母亲的教育水平与两个牙列的龋病患病率均显著相关，乳牙龋（OR=4.87）与DMFT>0相关。恒牙列中最常受影响的牙齿是下颌第一磨牙，乳牙列中是下颌第二磨牙。与其他牙面相比，两个牙列的咬合面最常受影响。
本研究确定了印度学龄儿童乳牙列和恒牙列龋病的临床、社会经济和行为决定因素。关键词：龋病经历、社会经济地位、釉质缺陷、牙面分布。
