Background: Significance of an index is well-known to the scientific community. However, the choice of a best index among multiple similar indices is a challenge. Considering the differences in scoring criteria, number of teeth examined, clinical applications, etc. the need to compare different calculus indices on similar set of teeth was desirable. Aim and Objective: The aim of this study is to compare 6 different calculus indices to assess their inter- and intra-examiner reliability and reproducibility. In addition to this, the objective was to assess their simplicity, time consumption, ease of clinical application and suitability for clinical trial and/or epidemiological purpose. Materials and Methods: Two examiners examined 50 randomly selected patients, to evaluate six different calculus indices, viz. Oral hygiene index, Sign grading system, periodontal disease index, Calculus surface severity index, Volpe-Manhold index and Marginal line calculus index. Few patients were reassessed by the same examiner to detect the reproducibility. Raw data thus obtained was filtered, tabulated and subjected to statistical calculations. Conclusion: There was no single index which completely fulfils all the ideal requisites to the score 10 on a VAS scale. However, within the limits the study it could be said that Sign Grading System has combined advantages of OHI and PDI and can be included in other basic and/or clinical studies.
