The objective of this study was to establish the correlation between an index for caries treatment needs and an index for caries lesions detection and evaluation. A cross-sectional study was performed on three samples of children aged 3 (n = 302), 5 (n = 183), and 11-14 years old (n = 60), attending early childhood centers and schools in the cities of Avellaneda, Rio Grande, and Buenos Aires. Dental caries treatment needs were estimated on every child through the Caries Treatment Needs Index (CTNI) for programming resources allocation. Also, a diagnosis of dental caries was made according to ICDAS II criteria. After the diagnostic procedures, a dental care program was developed. The ICDAS II variable was operationalized by grouping the codes into four categories: G1: code 0; G2: code 1-2; G3: code 3; G4: code 4-5-6. Measures of central tendency and dispersion were calculated for both variables, and the correlation was calculated using the Spearman coefficient. Results revealed that in the group of 3-year-old children, a significant correlation was observed in G1 (rho = -0.822); G2 (rho = 0.330); G3 (rho = 0.509) and G4 (rho = 0.710) between both indexes. For the group of 5-year-old children, a significant correlation was observed in G1 (rho = -0.821); G2 (rho = 0.260); G3 (rho = 0.344) and G4 (rho = 0.840). In the group of children 11-14 years of age, a significant correlation was observed in G1 (rho = -0.692); G3 (rho = 0.437) and G4 (rho = 0.764). The indices analyzed in this study (CTNI and ICDAS II) show reasonable equivalence for use in clinical and epidemiological studies based on the statistical analysis.
