If your search refers to a "dental index" (a scoring system for oral health) published or updated in 2007, it likely refers to clinical metrics used by organizations like the or the CDC :
In 2007, a critical paper titled How much does the DMFT index underestimate the need for restorative care? was published in the Journal of Dental Education . Researchers compared clinical exams (looking at the mouth) to exams using . They found that relying on the standard DMFT alone (no X-rays) underestimated the D (Decayed) component by an average of 1.75 surfaces . There was a 44% probability that the caries value would be lower than the actual value without radiographs, leading to diagnostic errors.
The 2007 update specifically clarified the indexing of supernumerary (extra) teeth and impacted teeth, which had been a source of coding errors in the 1990s. For researchers looking for the the FDI standard is usually the document they require, often produced by the WHO (World Health Organization) in their oral health surveys that year.
A landmark multicenter study from Finland, titled "Computed online determination of life-long mean index values for carious, extracted, and/or filled permanent teeth," demonstrated the power of modern data analysis. Researchers at the University of Oulu developed a system to mine data from the electronic dental records of over 153,000 patients of all ages. By automatically calculating DS (Decayed Surfaces), M (Missing Teeth), and FS (Filled Surfaces) values, they could track oral health trends over a lifetime.

Overview
: This 2007 model allowed paleontologists to find a single fossilized molar and accurately calculate the size and shape of the missing adjacent teeth, completely transforming how hominid and mammalian fossil indexes are reconstructed. 3. Cinematic Context: The 2007 Film Teeth
These indices measure the health of the gums and supporting structures of the teeth.
