In areas with low caries prevalence, indices are needed for caries detection, which can also be used to identify initial lesions.


The aim of this study was to assess the caries prevalence among 12-year-olds using ICDAS criteria and to investigate the influence of independent variables on the findings.


The study was conducted in two regions of Germany. In Region 1, children received regular school-based prophylaxis, including fluoride varnish 2×/yr. In Region 2, there was no use of fluoride varnish in schools. Information on different factors influencing the outcome variable of caries experience was collected using structured questionnaires. DF-S values were calculated at different ICDAS cut-off points. To compare the mean caries scores of the subgroups, nonparametric tests were performed. Variables associated with caries were included in a binary logistic regression analysis.


At D(1-6) FS and D(1+2) FS level, the differences between the regions were statistically significant (P = 0.005 and P = 0.01, respectively). Regression analysis identified the variables 'use of fluoridated toothpaste', 'fissure sealants', and 'ethnic origin' as factors significant to the prevention of caries at various stages.


In a population with low caries prevalence, significant differences between subgroups could only be found when initial lesions were included.
