The purpose of the study was to determine the effectiveness of various caries activity tests, including Dentocult SM, Cariostat and Dentobuff for screening children with high risk for dental caries increment. Dental caries were detected on a tooth-surface basis in addition to microbiological tests carried out on 210 children aged 0 to 6 years in Kitakyushu City. They were examined a total of 5 times at six month intervals for a period of 2 years. The prevalence rate of mutans streptococci measured by Dentocult SM gradually increased with age in the 0.5-3.4-year-old group, and it was about 80% in the 3.5-6.0-year-old group. The mean numbers of decayed and/or filled tooth-surfaces (dfs) were significantly higher (p<0.05 or p<0.01) in children with higher scores on the Dentocult SM and Cariostat tests than in those with lower scores. The mean numbers of increased decayed and/or filled tooth-surfaces (⊿dfs) were significantly higher (p<0.05 or p<0.01) in children with higher scores on the Dentocult SM and Cariostat tests than in those with lower scores. Every 6-month caries increment was positively correlated (p<0.05 or p<0.01) to scores of Dentocult SM and Cariostat, and the numbers of baseline dfs in the 1.5-4.4-year-old group. In particular, in caries-free children every 6-month caries increment was positively correlated (p<0.05 or p<0.01) to scores of Dentocult SM. Sensitivity and specificity in screening high-risk children for dental caries increment were over 60% in scores of 2 or more, 3 on the Dentocult SM test and numbers of 1 or more beseline dfs than any other caries activity tests. In caries-free children, those were highest in score of 1 or more on the Dentocult SM test. Relative risk of dental caries evaluated by the level of mutans streptococci was highest for the 6-month period than for any other period. These results suggest that it is better to use the Dentocult SM test for effectively screening 0-6-year-old children with high-risk for caries increment. This might enable more efficient preventive care to be provided for selected children.
