Abstract
OBJECTIVE: 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. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.
