Abstract

For the purpose of knowing the actual condition of between-meal eating habit and the relationship between the habit and the dental caries in preschool children, we conducted a questionnaire survery. From the answers by questionnaire and caries prevalence in 26 preschool children and 50 primary school children, we obtained following results : Frequency of intake was higher in preschool children than in primary school children in regard to solid snack foods, solid sweets and sweet beverages. Considering these differences and other factors comprehensively, preschool children were considered to be exposed to risky condition compared to primary school children in view of dental caries attack. From the statistical analysis about preschool children using the correlation coefficient between dental caries and the between-meal eating habit, significant correlation was observed in the intake of green tea or ptisan, the regularity in intake, the liking for solid sweets, the liking for sweet beverages, the daily frequency of solid sweets, and the daily frequency of sweet beverages. From the statistical analysis using Fisher's exact probability test, it was suggested that the occasional or usual intake before bedtime, the strong liking for sweet beverage, the everyday intake of solid sweets and low frequency in intake of green tea or ptisan were considered to be risk factors influencing on dental caries occurrence in the preschool children.
