[Simplified caries index for ages 4 to 6 and 7 to 10 (deciduous and mixed dentition)]

The purpose of this research is to obtain a simplified caries index. Four hundred and twenty children, both sexes, 4 to 10 years of age were divided in two groups: 4-6 years and 7-10 years. For caries prevalence, on the deciduous dentition, we used a modified GR JEBBEL index and for permanente teeth, the criteria established by KLEIN et alii, 1938. Considering the cumulative effects of caries, in the mixed dentition, we considered the sum of dmfs and DMFS. A simplification of the total index was performed, for the ages 4 to 6 years considering the teeth 54, 61, 75, 82 and for mixed dentition we added the tooth 26 and 26. The results showed in both dentition, that simplified caries index showed significant correlation with the total index.
