DMTF Index is still frequently used in dental caries surveys, although new indexes have been presented.
But did the dmft index suffer any modification in the last years?
DMFT and dmft are still the same as the were previously. But most of time in the d/D score the depth of the caries lesion is scored (enamel lesion / dentin lesion / lesion reaching to pulp).
Other scoring systems are also more frequently used (ICDAS etc). Please take a look to the research you want to compare your research with in deciding what and how to score.
The CAST (Caries Assessment Spectrum and Treatment) index is new. It is has been use recently.
Nyvads criteria...CAST index....ICDAS II have been proved to be valid indices recently to measure caries experience.all this indices considers both cavitated and non cavitated lesions...but for large population surveys WHO modification 1997 is still followed though it considers only cavitated lesions..
WHO Basic Oral Health Survey 2013 is the recent one which recommends calculation of DMFT/ dmft from dentition status index
