Objectives: This multicentric cross sectional study aimed to determine the prevalence of dental caries, its’ severity and activity among Brazilian and Argentines schoolchildren.Methods: The sample comprised of 406 schoolchildren in Brazil (Belo Horizonte) and 241 schoolchildren in Argentina (Córdoba), selected by convenience. The prevalence and severity of dental caries were measured by dmft and DMFT index according to WHO criteria. The sample third that had high caries experiences was identified using Caries Index (SiC). Caries activity was assessed by a simplification of the diagnostic criteria proposed by Nyvad et al.Results: The prevalence of caries free (dmft and DMFT = 0) in Brazil was 45.7% and 19.9% in Argentina. The dmft was 1.48 (95% CI: 1.26 1.71) and 2.38 (95% CI: 2.0 2.72) among schoolchildren in Brazil and Argentina, respectively. The DMFT was 0.57 (95% CI: 0.45 0.68) in Brazil and 0.81 (95% CI: 0.63 0.96) in Argentina. In both countries, decayed component was the most frequent condition observed. The prevalence of caries activity was 43.0% and 23.2% in Brazil and Argentina, respectively. Among subjects with caries experience (dmft> 1 and / or DMFT> 1) the prevalence of caries activity was 77.5% in Brazil and 26.4% in Argentina. In SiC group, DMFT was 2.20 (95% CI: 1.95 2.20) in Brazil and 2.17 (95% CI: 1.91 to 2.43) in Argentina. The dmft in SiC group in Brazil was 3.37 (3.01 to 3.72) and in Argentina was 5.56 (5.04 to 6.07).Conclusions: In both countries, the prevalence of caries in primary and permanent teeth was very low according WHO, although prevalence of children with experience of the disease is high. Concentration of load and caries activity was found in groups of the diseases’ polarization, for both primary and permanent teeth. It is noteworthy that caries in the primary dentition is a relevant problem that needs targeted efforts in Brazil and Argentina.
