Three-Year Randomized Trial of Professionally Applied Topical Fluoride Gel Comparing Annual and Biannual Applications with/without Prior Prophylaxis
Bibliographic record
Abstract
The twice yearly application to children's teeth of acidulated phosphate fluoride (APF) gel in dental trays preceded by a professionally rendered 'dental prophylaxis' has become the standard and most commonly used dental chairside procedure for prevention of dental caries. This study was a randomized, 3-year, community-based clinical trial of professionally applied APF gel involving the use and non-use of a prior dental prophylaxis and annual and biannual APF applications for children in age groups 6-7 (n = 176) and 10-11 (n = 153) years initially, who are likely at high risk of future dental caries. The 3-year results of this study show no significant effect on dental caries reduction of either a prior prophylaxis or annual versus biannual APF gel applications. A significant reduction in the frequency of provision of these dental services, limited to high caries risk patients only, is recommended.

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.
