Background: Dental caries is an irreversible dental disease. The incidence of dental caries in children was increased by 60-90%. Dental caries can be recognized by various factors. Caries risk status needs to be adjusted so that caries development can be inhibited as early as possible. Methods of caries risk measurement are PFRI and cariostat caries prediction. The aim of this study was looked at the risk factors of childhood caries by using combination of PFRI and Cariostat. Method: This study was an observational analytic study with laboratory study approach. Based on the time it was the cross sectional study. The samples were 36 children in TK Maryam Jl. Manyar Sambongan Surabaya. This study was used primary data, then the data were analyzed in Microbiology Laboratory of FKG Airlangga University Surabaya. Data analysis was conducted with Kolmogorov-Smirnov and Spearman Correlation. Results: There were 12 children suffered high dental caries (>5), 12 children suffered moderate dental caries (3-4), 12 children suffered low dental caries (0-2). Measurement of caries risk used Cariostat and PFRI was showed a strong correlation (p>0.05) Conclusion: The correlation of caries risk test score using Cariostat caries activation test and PFRI that correlated with deft index are has no different results.
