Work out dental caries index (dmft) instantly with clear inputs, formula shown and shareable results.
Adds decayed, missing and filled teeth to give the DMFT index, and reports the restorative index showing what share of affected teeth have been treated.
DMFT
DMFT = decayed + missing + filled teeth; restorative index = filled / (decayed + filled) x 100. WHO bands: very low <1.2, low 1.2-2.6, moderate 2.7-4.4, high 4.5-6.5, very high >6.5
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
DMFT counts teeth; DMFS counts surfaces and is more sensitive to small changes.
Teeth missing for reasons other than caries, such as orthodontic extraction or trauma, are not counted.
