Abstract |
The purpose of this study was to investigate the difference between the children who experienced nursing caries and the children who were caries-free in the prevalence of enamel hypoplasia and DMF rate and to analyse causal factors from questionnaires. Oral examination was performed on 101 children(nursing caries group-45, caries-free group-56)in the 1994 at first, later in 1999. Parents were asked to write questionnaires. As a cotrol group, 50 children were chosen randomly. The results obtained from this study were as follow: 1. The prevalence of enamel hypoplasia of the children who experienced nursing caries was higher significantly than that of the all of the examined children (P<0.01). 2. DMF Tate of the children who experienced nursing caries was higher significantly than that of the children who were caries-free (P<0.01), and higher than that of the all of the examined children also(P<0.05). 3. The children who experienced nursing caries performed tooth brushing less frequently (P<0.05) and started tooth brushing later than the children who were caries-free (P<0.01). 4. The children who experienced nursing caries ate cariogenic food more frequently(P<0.05) and had higher preference(P<0.05) than the children who were caries free. 5. The children who experienced nursing caries showed lower frequency of periodic dental examination than the children who were caries-free or centre) group(P<0.05). |
