Abstract

fetched live from OpenAlex

OBJECTIVE: Evidence of increased apoptosis is observed in periodontitis and may be associated with destruction of the periodontal tissue caused by the increased cell death, with the release of danger signals and subsequent stimulation of the proinflammatory processes. However, the exact mechanisms associated with these processes remain unclear. This study aimed to investigate the presence of the periodontal pathogen Treponema denticola, apoptosis, high mobility group box 1 as a damage-associated molecular pattern, and several inflammatory markers in periodontitis and gingivitis subjects. MATERIALS AND METHODS: Soft tissue specimens from gingival tissues of periodontitis and gingivitis patients were used for immunohistochemical and immunofluorescence staining of T. denticola chymotrypsin-like proteinase (CTLP), apoptosis markers, high mobility group box 1, Toll-like receptor 4, inflammatory cell markers, and proinflammatory cytokines. RESULTS: Treponema denticola was detected in all periodontitis-affected tissues. This was associated with a significant increase in the number of apoptotic cells, including macrophages, alterations in the expression of high mobility group box 1 and its receptor, and increased levels of proinflammatory cytokines compared with gingivitis. CONCLUSIONS: In summary, the presence of T. denticola (especially its CTLP), apoptosis, high mobility group box 1, and inflammatory markers suggests their potential involvement in the pathogenesis of periodontitis.

Teacher imitation

Not 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.
