Abstract
The major indications of a successful inflamed-pulp-capping procedure are the formation of a dense calcified dentin barrier and the preservation of healthy pulp tissue concomitant with elimination of inflammation. Our aim is to evaluate the effects of an injectable silver-doped bioactive glass/chitosan hydrogel (Ag-BG/CS), as a pulp-capping material, and explore the molecular mechanisms of Ag-BG/CS in regards to its bioactive and anti-inflammatory properties. First, the structure and component of the material were analyzed by scanning electron microscopy. Then, the downstream molecular mechanisms and anti-inflammatory effects were characterized by quantitative polymerase chain reaction (qPCR) and Western blot. Finally, a preclinical model of rat pulpitis was used to explore the potential of Ag-BG/CS in controlling pulp inflammation in vivo. The results showed that Ag-BG/CS induced stronger reparative dentin formation and enhanced preservation of vital pulp tissue when compared to the mineral trioxide aggregate (MTA) which is the currently used clinical standard. Ag-BG/CS also significantly increased the phosphorylation of p38 and ERK1/2(p42/44) of dental pulp cells, indicating that Ag-BG/CS enhanced pulpal repair through the mitogen-activated protein kinase (MAPK) pathway. This novel material may represent a superior solution for dental pulp-capping clinical scenarios with specific advantages for cases of early diffuse pulpitis in immature permanent teeth.

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 it
