This study aimed to determine the prevalence and related factors of deciduous caries in 3-5-year-old preschool children in Chongqing city. Results will be used to provide a basis for the establishment and adjustment of prevention and intervention of caries in preschool children.
We referred to the Fourth National Oral Health Epidemiological Survey. Data included caries prevalence in preschool children, and the questionnaires were distributed to children' parents in Chongqing city. Results were inputted by Epidata 3.1 and statistically analyzed using SPSS 21.0.
A total of 1 350 preschool children were included in the study. We found that maxillary deciduous central incisor and mandibular deciduous molars were susceptible to decay. The prevalence of primary teeth caries in preschool children in Chongqing city was 51.4% (694/1 350). The mean decayed-missing-filled-teeth (dmft) index was 2.34. The caries prevalence and mean dmft between age groups were statistically significant (P<0.01) and increased with age (P<0.05). However, except the 5-year-old group (P<0.05), no significant difference in caries prevalence rate and mean dmft was found between male and female children (P>0.05). Approximately 61.7% of caries cases were concentrated in a small number (36.1%) of individuals. Multivariate Logistic regression analysis showed that age, highest educational level of parents, intake frequency of sweetened beverages and carbonated drinks, toothache or similar discomfort experience over the past year, dentist visits, and parents' assessment of teeth and oral health status of children were the factors influencing the prevalence of deciduous caries (P<0.05).
More than half of the preschool children had dental caries. Majority of caries were concentrated in a small number of individuals. The age of children, highest educational level of parents, intake frequency of sweetened beverages and carbonated drinks, toothache or discomfort experience over the past year, dentist visits, and parents' assessment of teeth and oral health status of children were associated with the prevalence of deciduous caries.
本研究旨在确定重庆市3至5岁学龄前儿童乳牙龋病的患病率及相关因素。研究结果将为制定和调整学龄前儿童龋病的预防与干预措施提供依据。
参考第四次全国口腔健康流行病学调查。数据包括学龄前儿童龋病患病率，并向重庆市儿童家长发放问卷。结果通过Epidata 3.1录入，并使用SPSS 21.0进行统计分析。
本研究共纳入1350名学龄前儿童。我们发现上颌乳中切牙和下颌乳磨牙易患龋病。重庆市学龄前儿童乳牙龋病患病率为51.4%（694/1350）。龋失补牙面均（dmft）指数为2.34。各年龄组之间的龋病患病率和平均dmft有统计学意义（P<0.01），且随年龄增长而升高（P<0.05）。然而，除5岁组外（P<0.05），男童和女童之间的龋病患病率和平均dmft无显著差异（P>0.05）。约61.7%的龋病病例集中在少数（36.1%）个体中。多因素Logistic回归分析显示，年龄、父母最高学历、含糖饮料和碳酸饮料摄入频率、过去一年的牙痛或类似不适经历、看牙医次数以及父母对孩子牙齿和口腔健康状况的评估是影响乳牙龋病患病率的因素（P<0.05）。
超过半数的学龄前儿童患有龋齿。多数龋齿集中在少数个体中。儿童年龄、父母最高学历、含糖饮料和碳酸饮料摄入频率、过去一年的牙痛或不适经历、看牙医次数以及父母对孩子牙齿和口腔健康状况的评估与乳牙龋病患病率相关。
