Oral disease within different population groups can be indicated by the proportion of people within that group who have decayed, missing or filled teeth.

Depending on whether the teeth are deciduous (baby teeth) or permanent (adult teeth), either a dmft (for baby teeth), a DMFT (for adult teeth) or a dmft/DMFT (for both) score is used to measure numbers of decayed, missing or filled teeth.

For more information see Dental & oral health publications.
