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.

Multiparametric Quantitative MRI of Peripheral Nerves to Differentiate Demyelinating From Axonal Polyneuropathies

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Differentiating demyelinating from axonal polyneuropathies helps for accurate diagnosis and treatment. However, the current clinical tools lack sensitivity to confirm demyelination in peripheral nerves, particularly for proximal nerves.

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.

The effect of bioactive membrane in alveolar ridge preservation: A double‐blind randomized clinical trial

Journal of Periodontology, EarlyView.
Abstract Background This randomized controlled trial aims to evaluate alveolar ridge preservation (ARP) with or without a biologically active amnion–chorion membrane (BACM). Methods Thirty patients requiring tooth extraction in the esthetic zone were randomly assigned to 2 groups.

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.

Aging and periodontitis increase brain dissemination of oral bacteria

Journal of Periodontology, EarlyView.
Abstract Background The microbiome is a dynamic system that changes throughout life. Studies have revealed the relationship between periodontal disease and the oral microbiota; however, the impact of periodontal disease on the expression of senescence markers and on the inflammaging of the oral and systemic microbiome remains unclear.
