Another critical component of the dental index landscape in 2007 was the Index of Orthodontic Treatment Need (IOTN). This two-part index helped determine which patients required orthodontic intervention for functional reasons versus purely aesthetic ones. By using a standardized grade from 1 to 5, dental boards could prioritize government-funded or insurance-covered treatments for those with the most severe malocclusions.
It is a prime example of "digital epidemiology." It proved that could be calculated automatically from routine dental records without manual exams, paving the way for modern population health surveillance. index of teeth 2007

The DMFT index is simple: For a patient, a dentist examines all 32 permanent teeth and counts how many are: It is a prime example of "digital epidemiology
Widely used in the United States, this index assigns numbers 1 through 32 to permanent teeth, starting from the upper right third molar (wisdom tooth) and ending at the lower right third molar.
For many years, the DMFT/dmft index was the cornerstone of oral epidemiology. It records: Decayed teeth. M/m: Missing teeth due to decay. F/f: Filled teeth.
