Background: Accurate diagnosis, reporting of caries and its consequences, is absolute mandate for planning an efficient, effective community health-care program. Literature reports indicate shortcomings of existing caries assessment tools. Caries assessment spectrum and treatment (CAST) is novice caries quantification tool, which quantifies the entire spectrum of carious lesions. This tool records give an insight into the status of restorations along with various progressive developmental stages of dental caries. This instrument has been validated for face, content, and construct by an expert group, and currently, its usage is on the rise. Aim: The aim of this study was to report the reliability of this assessment tool with regard to the primary and permanent dentition of school children and adults belonging to a south Indian district. Materials and Methods: A cross-sectional study was carried out by two trained and calibrated examiners by examining 192 school children in the age-group between 4 and 6 years and 262 adults between 19 and 69 years. The study sample was reexamined by the same examiners after a gap of 4 weeks. The κ coefficient values and percent of agreement were calculated for the data recorded from the study subjects. Results: The analyzed data showed moderate intra-examiner and inter-examiner reproducibility for either of the dentition as revealed by κ coefficient values (0.80–0.89). Inter- or intra-examiner agreement was found to be substantial to almost perfect (percent agreement above 90%) with respect to both the age-groups. Conclusion: The CAST tool seems quite promising to be the future for quantifying caries spectrum for a community or an individual.
