Which instrument is used to count decayed, missing, and filled surfaces/teeth in DMFS/DMFT?

Explanation:
Counting decayed, missing, and filled surfaces/teeth in DMFS/DMFT comes down to detecting caries and restorations on each tooth surface during a clinical exam. The dental explorer is used because its tactile probing lets you feel changes in texture and softness that indicate decay and confirm whether a surface is decayed, missing due to caries, or filled. By systematically examining every tooth surface with a mirror and explorer, you can tally the DMFS/DMFT components accurately. Rulers and calipers measure dimensions, not caries status, and X-rays can reveal hidden lesions but aren’t the primary tool for counting in this index.
