Independent Prognostic Value of Natural Tooth Count Versus Posterior Teeth Occlusion in Resected Pancreatic Cancer

Journal of Hepato-Biliary-Pancreatic Sciences, EarlyView.
ABSTRACT Background/Purpose Prognostic significance of preoperative patient‐related factors, including oral health status, in pancreatic ductal adenocarcinoma (PDAC) remains unclear. We evaluated the association between preoperative factors—particularly oral health parameters—and long‐term survival after curative PDAC resection.

Peri‐implant disease pathogenesis animal models: Consensus report of Workgroup 1 of the IADR Implantology Research Group Best Evidence Consensus Symposium on Peri‐Implant Disease and Its Treatment

Journal of Periodontology, EarlyView.
Abstract Background The pathogenesis and etiology of peri‐implantitis demand a deeper understanding to lead to successful treatment modalities. Animal models of peri‐implantitis pathogenesis offer unique insights but their translational impact requires consideration of implant biomaterials science.

Dasatinib and quercetin prevent alveolar bone loss in aged mice

Journal of Periodontology, EarlyView.
Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.

Microbial burden of periodontal diseases and its clinical application: The stage, grade, and furcation matter

Journal of Periodontology, EarlyView.
Abstract Background Periodontal diseases are associated with dysbiotic oral microbial communities, but clinically applicable measures that reflect microbial burden across disease severity and progression remain limited. This study aimed to assess the oral microbial burden of periodontal diseases by evaluating salivary and subgingival lipopolysaccharide

Associations between periodontal inflammation and OHIP‐14 scores: A cross‐sectional study

Journal of Periodontology, EarlyView.
Abstract Background More evidence is needed to assess the association between periodontitis and Oral Health‐Related Quality of Life (OHRQoL) quantitatively. We hypothesized that periodontal inflammation is correlated with a worsening in quality of life and aimed to test this in this study.
