Traumatic dental injury in 12--14-year-old Ontario schoolchildren: Etiology and environment, its impact on quality of life, frequency and use of mouthguards
Bibliographic record
Abstract
Objectives. To investigate the etiology, place of injury, and social impact of traumatic dental injuries, and the frequency of mouthguard use among 12 and 14-year-old Ontario schoolchildren. Methods. Age- and gender-matched, case-comparison study of 270 children from two Ontario communities. Data sources: Clinical data collected by trained dental hygienists (Dental Trauma Index, DMFT and AC-IOTN) and mailed questionnaire. Results. Falls at home and school were the most common cause of injury. Untreated trauma cases experienced more social and functional impacts than comparisons. Only 5% of children wore mouthguards. Over 50% reported that they "have never been told to wear a mouthguard."Conclusion. Despite the low prevalence of dental injuries, these injuries still had a significant social impact on adolescents. While injuries could be prevented with the use of mouthguards, coaches, teachers, and health professionals were not providing children or parents with adequate information about the benefits of their use.

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.
