Correct answer: D — Cumulative caries experience in permanent teeth (decayed, missing due to caries, and filled)
The DMFT (Decayed, Missing, Filled Teeth) index is the most widely used measure of dental caries experience in permanent dentition. D = untreated decayed teeth, M = teeth missing due to caries, F = filled (restored) teeth. It is a cumulative index (it never decreases) and does not distinguish between treated and untreated disease. The dmft index is the primary dentition equivalent. The DMFS/dmfs index uses surfaces instead of whole teeth.
