Myeloid A20 Regulates Periodontal Tissue Integrity and Temporomandibular Joint Structure

Journal of Periodontal Research, EarlyView.
Dysregulation of A20 signaling has been implicated in several immune‐mediated diseases, including rheumatoid arthritis and psoriasis, conditions characterized by excessive NF‐κB activation and inflammatory tissue damage. The structural alterations observed in this model suggest that impaired regulation of innate immune signaling may increase ...

High‐Frequency Ultrasound Compared to Periodontal Probing for Pocket Depth Assessment: A Diagnostic Accuracy Study

Journal of Periodontal Research, EarlyView.
High‐frequency ultrasound (US‐PD) and probing pocket depth (PPD) estimations were conducted in 539 teeth from 34 participants. The mean PPD was 1.83 ± 0.55 mm, and US‐PD was 1.86 ± 0.64 mm. The mean absolute deviation was 0.54 ± 0.45 mm, mean difference based on Bland–Altman analysis was −0.03 mm, and ROC analysis showed that HFUS has a fair ...

Phloridzin Mitigates Aging‐Associated Periodontitis by Restraining Inflammatory Cell Death

Journal of Periodontal Research, EarlyView.
Phloridzin attenuated oxidative stressinduced senescence, inflammatory responses, and osteogenic dysfunction in HPDLCs. In an aging‐associated experimental periodontitis model, phloridzin alleviated alveolar bone loss, suggesting its potential to maintain periodontal tissue integrity under aging‐related inflammatory conditions.
