In Vivo Resistance of Coronally Induced Bacterial Ingress by an Experimental Glass Ionomer Cement Root Canal Sealer
Bibliographic record
Abstract
The resistance of an experimental sealer (KT-308) to bacterial ingress was assessed in six beagle dogs. In four mandibular premolars per dog, canals were prepared, filled with condensed gutta-percha and either KT-308 or Roth 801 cement (n = 24 roots), and the pulp chambers inoculated with plaque. Two additional premolars per dog were similarly root-filled, but not inoculated (n = 12 and 11, respectively). One incisor per dog was inoculated, but not root-filled (n = 6). Dogs were terminated after 6 months, and jaw blocks were retrieved and processed for light microscopic examination of the periapical tissues. Inflammation about the inoculated roots was significantly lower (p < 0.03) for KT-308 (17%) than Roth 801 cement (46%). Inflammation about the noninoculated roots did not differ significantly between KT-308 (8%) and Roth 801 cement (36%). This study demonstrated a better functional efficacy of KT-308 than of Roth 801 cement, and validated this in vivo model for assessment of root filling materials.

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.
