Development of a Risk Prediction Model for Assessing Dental Readiness in the Canadian Armed Forces
Bibliographic record
Abstract
INTRODUCTION: The establishment and sustainment of a high state of dental readiness in the Canadian Armed Forces (CAF) are the primary missions of the Royal Canadian Dental Corps. The objective of this study was to develop a risk prediction tool to estimate dental readiness in active CAF personnel. MATERIALS AND METHODS: The prediction model was developed to predict the classification of non-deployable (yes/no) within 12 months (primary) and 18 months (secondary) using both dental history data (including dental attendance, restorations, root canals, and third molar status) and demographic information. Two cohorts were used for development: a recruit cohort who enrolled between April 2016 and March 2017 and a longer-serving member (LSM) cohort who had their recall dental exam between May 2014 and October 2014. Each group was followed until April 26, 2018. Elastic net logistic regression models were used to create the models. Model performance was evaluated using area under the curve, F1, and the Brier score. RESULTS: The recruit cohort included 2,828 individuals and the LSM cohort included 2,398 individuals. Overall, the classification of non-deployable occurred in 5.1% of the study population within 12 months and 9.6% of the population within 18 months. The models predicted the outcome with an area under the receiver operating curve of 0.77 in recruits and 0.70 in LSMs. CONCLUSION: The prediction model shows potential but its performance and usability could be further improved through the consistent collection of high quality, discretely entered, epidemiological data following standardized diagnostic terminology and coding. A recalibrated and automated version of this model could assist in decision making, resource allocation, and the enhancement of military dental readiness.

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; a candidate call from one teacher head, not a consensus.
