Abstract

The purpose of study was to investigate the etiologic factors of maxillary primary anterior caries. The subjects of study were 401 preschool children, 214 boys and 187 girls, from 36 to 71 months old of randomly selected seven nurseries in Iksan city. The prevalence of maxillary primary anterior teeth was cross-analyzed with gender, age, breast feeding or bottle feeding, length of feeding, sweet snack intake frequency, beginning of toothbrushing, and toothbrushing frequency per day. The prevalence was 43.0% in boys and 26.7% in girls, and there was significant association between the prevalence and gender in cross analysis(P<0.01). The prevalences of the shorter than 2 years of feeding group, the from 2 to 3 years group, and the longer than 3 years group were 31.0%, 43.2%, and 63.2%, respectively, and there was significant association between the prevalence and the length of feeding(P<0.01). Daily intake of sweet snacks had a significant association with the prevalence(P<0.05). There was no significant association between the prevalence and the variables of age, breast feeding or bottle feeding, beginning of toothbrushing, and toothbrushing frequency per day(P>0.05).
