The DMFT score (Decayed, Missing, and Filled Teeth) is used to measure the dental health of an individual. According to the WHO Modified DMFT Index 1987, the score is calculated by adding the number of decayed, missing, and filled teeth. In this case, although there are fractured teeth and extracted molars, the temporary restorations and chalky spots do not contribute to a score of decay, missing, or filling. The correct DMFT score is 0, indicating no untreated dental caries or missing teeth as per the index.
