Results: The caries status in permanent teeth after the one-year follow-up period was as follows: in caries free group, DMFS increment was 1.15 ± 1.66; 25% children showed an increase of 1 - 2 caries surfaces; in high caries group, DMFS increment was 1.64 ± 1.46; 53.6% children showed an increase of 1 - 2 caries surfaces. There were significant differences not only in the percentage increases of children with caries but also in the DMFS increment between the 2 groups (caries free and high caries children) (p<0.001).
