Abstract

fetched live from OpenAlex

A method to calibrate examiners for field studies of dental caries was investigated. A total of 200 carious teeth were mounted in 40 plaster blocks so that 920 surfaces were available for examination with a curved probe, using WHO criteria. The results of two examinations of the teeth 1 week apart by 3 experienced and 4 new examiners and 1 year apart by two experienced examiners were compared. The intra-examiner and inter-examiner reproducibility was high for the experienced examiners; between experienced and new examiners the reproducibility fluctuated. Scanning electron microscopic examination of the tips of probes indicated that the sharpness was only slightly decreased within their usual frequency of use. The calibration system used is recommended for the training of examiners for dental caries field studies.

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.

Not 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.
