Abstract

 The aim of this study was to investigate predictive factors related to dental caries in the deciduous dentition that developed during the period from 3 to 5 years old in a cohort study. The subjects were 185 children aged 3 years old who went to 7 preschool facilities comprising nursery schools or kindergartens in Fukuoka in 2004. The outcome variable was the caries increment from 3 (2004) to 5 (2006) years old. Explanatory variables were collected from questionnaires in 2004 and the results of dental examinations in 2004 and 2006. Children at 3 years of age with dental caries in the deciduous dentition numbered 53 (35.1%), which increased to 84 (55.6%) by 5 years of age. Children who had new caries in the deciduous dentition for the two years numbered 75 (49.7%). As the variable of interest was children with/without new caries in the deciduous dentition, multivariate logistic regression analysis was applied to two statistical models. In one model, the subjects were limited to 98 (64.9%) caries-free children at the baseline (3 years of age), while in the other, the subjects were all 151 children. In the former model, the only significant explanatory variable was the non-use of toothpaste (odds ratio: 2.7, 95% CI: 1.10-6.76, p = 0.030). In the latter model, the only significant explanatory variable was caries experience at 3 years old (odds ratio: 10.7, 95% CI: 4.54-25.48, p <0.001). The use of toothpaste had a caries-preventive effect because it contained fluoride. Caries experience at 3 years of age influenced the increment of dental caries in the deciduous dentition during the period from 3 to 5 years old; therefore, the prevention of caries in the deciduous dentition from birth to 3 years old is important. The use of fluoride toothpaste from an early stage of life is necessary to reduce the prevalence of dental caries in the deciduous dentition effectively after 3 years of age.
