Abstract
Epidemiologic evidence indicates that the prevalenceof dental caries in the permanent dentition amongUnited States and Canadian children and adoles-cents has been decreasing.1,2 For example, in 1958–1959 the mean decayed, missing or filled permanent teeth (DMFT) score for 13-year-old children in Toronto was 5.7; in 1999–2000, it had decreased to 1.1.3 Dental caries, however, is still a significant problem. Currently, in the United States, 20 % of children between the ages of 2 and 4 years have detectable caries, and approximately 80 % of youth will have had a cavity by the age of 17 years.4 Although the prevalence of caries has been decreasing in the general population, it remains high among Canadian Aboriginal and Native Americans.5–12 A comparison of 2 national oral health surveys7,8 of Canadian Aboriginal children 6 and 12 years of age conducted in 1990–1991 and, most recently, in 1996–1997, found that the mean decayed, extracted or filled deciduous teeth (deft) score for 6-year-old children increased statistically significantly from 8.2 to 8.7, whereas the mean DMFT score increased nonsignificantly from 0.7 to 0.8. Overall, for children 12 years of age, there was little change in mean DMFT score (4.6 to 4.5). According to these surveys, 6-year-old Aboriginal chil-dren in Ontario had the highest deft score of the 9 regions in the survey; their mean score was 11.1 in 1990–1991,

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
