Which indices are used to quantify caries experience in an individual?

• A. CPI and CAL
• B. DMFT and DMFS
• C. VPI and API
• D. SBI and DMH

Answer: (B)

Understanding caries experience means looking at the history of caries a person has had, not only what is currently decayed. The best way to quantify this on an individual is with DMFT and DMFS. DMFT stands for decayed, missing, and filled teeth. It counts how many teeth have ever been affected by caries—whether they are currently decayed, have been lost due to caries, or have been filled because of prior decay. DMFS works similarly but counts affected tooth surfaces rather than whole teeth, giving a more detailed view of the caries experience across the mouth. Together, these indices reflect lifetime caries experience and are widely used to compare individuals and populations. The other options focus on areas such as periodontal status (gum health) or plaque/biofilm, or on indices that measure different aspects of dental health. They do not provide a direct measure of an individual’s caries experience, which is why DMFT and DMFS are the best fit.
