OBJECTIVE: To analyze whether two simplified indices, "DMF in 6 Teeth"(DMF6T) and "DMF in two quadrants" (DMF2Q), could be indicated for epidemiological surveys of oral health according to dental caries distribution. METHODS: The sample came from epidemiological data in 29 municipalities. A total of 2,378 examinations were done on 12-year-old schoolchildren. The mean DMFT from each locality was utilized to obtain three DMFT prevalence groups (low, moderate and high), for which the simplified indices were calculated. Statistical analysis was done using intraclass correlation and the Wilcoxon and chi-squared tests, with a significance level of 5%. RESULTS: Intraclass correlation between the DMFT index and the simplified indices ranged from 0.82 to 0.95 (p<0.05). No significant differences in the prevalence of the studied parameters were observed between the means of the DMFT and DMF2Q indices (p>0.05), although DMF6T showed differences. The proportions of decayed, missed and filled teeth were similar between the DMFT and DMF2Q indices (p>0.05). CONCLUSIONS: The simplified DMF2Q index can be used in epidemiological surveys in areas with low, moderate and high prevalence of dental caries. However, better evaluation of the DMF6T index needs to be made.
