Aim: The aim of this study is to compare the different caries diagnostic thresholds under epidemiological and clinical settings among 7-15 year old school children. Materials and Methods: A cross-sectional study was undertaken among 7-15 years old school children of Bangalore city. Total 738 children were enrolled in the study. General information was collected regarding oral hygiene practice and personal habits of the schoolchildren. Subsequently, examination was done under both the settings to record Decayed, missing and filled surfaces index for permanent teeth (DMFS) and Decayed, missing and filled surfaces index for deciduous teeth (dmfs) using the World Health Organization (WHO) and WHO + IL criteria. Results: The present study showed that both the settings (clinical and epidemiological) and diagnostic thresholds (WHO and WHO + IL), could influence the detection of carious lesions. Mean Ds under WHO + Initial lesions (IL) criteria (3.92 + 3.49) was nearly double of WHO criteria (1.88 + 2.73,) and the influence observed was more in 14 years of age, where mean Ds under WHO + IL criteria (5.43 + 2.5) which was more than double of WHO criteria (2.02 + 1.9). Conclusion: The choice of a diagnostic threshold (WHO and WHO + IL) and the conditions of examination (epidemiological and clinical) are important for the detection of caries.
