Changes in Caries Prevalence of Isle of Lewis Children between 1971 and 1981
Bibliographic record
Abstract
An increasing body of evidence suggests that dental caries prevalence among children and adolescents in the UK, some continental European countries and the US has shown a marked reduction in the past decade. Prevalence data collected from a 1971 survey conducted on children aged 5, 8, 11 and 14 years living on the Isle of Lewis (Scotland) has been compared with contemporary (1981) data from the same age groups in this community. In this island, there is little change or movement of population and a complete record of dental health measures over the past 10 years is available. The results confirm the general decrease found in the other localities mentioned. There is no fluoride in the drinking water and no appreciable use of fluoride rinses or tablets in this community. However, the toothpaste market has changed over the period from zero fluoride in 1970 to virtually 100% fluoride by 1976.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
