In vitro effects of fibrin hydrogel incorporated with Litsea cubeba essential oil on viability of periodontal pathogens and human gingival fibroblasts
Bibliographic record
Abstract
Background/purpose: essential oil (LC-EO) and test its antimicrobial property against key periodontal pathogens and cytotoxicity on human gingival fibroblasts (HGFs). Materials and methods: by the direct contact method. The cytotoxicity to HGFs was determined by MTT assay. Results: was 1.0 % (v/v) and 0.25% (v/v), respectively. The lowest cytotoxicity to HGF cells was observed at 0.0625% (v/v), yielding the cell viability of 73.65 ± 8.24 % at 24 h. Conclusion: Fibrin hydrogel with LC-EO effectively inhibited bacterial growth in a dose-dependent manner. Cytotoxicity assays also revealed concentration-dependent effects on HGF. Our results suggest the potential use of fibrin hydrogel with LC-EO as a novel adjunctive treatment in periodontal diseases.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
