Osseous (cemento-osseous) dysplasia of the jaws: clinical and radiographic analysis.
Bibliographic record
Abstract
OBJECTIVES: To explore the demographic characteristics and clinical features among patients with osseous (cemento-osseous) dysplasia (OD/COD) of the jaws and to determine the frequency of particular radiographic characteristics. METHODS: The charts and radiographic reports of 118 patients with OD/COD, obtained from the archives of the University of Toronto discipline of oral and maxillofacial radiology, were reviewed. Demographic and clinical data, radiographic findings and final diagnoses were collected and analyzed to determine typical characteristics. RESULTS: Of the 117 patients for whom age and sex were known, the majority (97 [82.9%]) were female; these female patients had a mean age (± standard deviation) of 44.3 ± 13.4 years. Eighty-three (72.2%) of the 115 patients for whom symptoms were known were clinically asymptomatic. Ninety-three patients (78.8%) had OD/COD at single sites (i.e., periapical OD/COD), and 25 (21.2%) had OD/COD at multiple sites (i.e., florid OD/COD). In addition, 15 (12.7%) of the cases were associated with one or more simple bone cysts, and 13 (11.0%) were associated with osteomyelitis. In most cases, the OD/COD was unilateral, with the lesion being located in the mandible, usually associated only with the posterior teeth. The lesions exhibited well-defined, sclerotic or corticated margins (108 patients [91.5%]) and were surrounded by a radiolucent border. Minimal effects on surrounding structures were observed. As well, 85 (72.0%) of the lesions were in the mixed radiolucent-radiopaque stage, with dense, cementum-like radiopacities. CONCLUSIONS: The majority of cases of OD/COD occurred in women in the fifth decade of life, and most cases were asymptomatic. OD/COD was more likely to present as solitary lesions but also occurred in association with simple bone cysts or osteomyelitis.

How this classification was reachedexpand
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.
