An Exploratory Study of Oral and Dental Health in Canada
Bibliographic record
Abstract
Healthcare practitioners agree that good oral health is a critical indicator of general health and wellness of a population. The lack of access to mandatory coverage for common issues such as cavities and non-surgical periodontal care often lead not only to medical problems, but also to loss of productivity. This trend is especially evident for older individuals and lower-income families. This paper discusses the results of our exploration of the annual Canadian Community Health Survey (CCHS), in order to further study the interplay between socio-economic factors and oral and dental health. To this end, we present the results when applying a number of machine learning algorithms to a CCHS data mart. Our results reaffirm that individuals' levels and sources of income are strong indicators of the number of dental visits per year. In addition, we found that younger adults and youth, who usually live in larger households, visit the dentist less frequently than all other survey respondents.

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.
