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.

Analysis of meshing performance of face gear with full tooth surface modification

Jixie chuandong
ObjectiveTo investigate the influence of a modified tooth surface on the meshing performance of face gear pair, a full tooth surface modification method for face gear was proposed to optimize their meshing performance.MethodsFirstly, the standard tooth ...

Unsupervised phenotyping of the periodontal architecture through high‐dimensional clustering of electronic health records: A multicenter study

Journal of Periodontology, EarlyView.
Abstract Background To identify novel periodontal phenotypes using unsupervised machine learning on a large‐scale, multicenter cohort, specifically characterizing disease patterns based on the “periodontal architecture” of localized structural failures (tooth mobility and molar furcation defects) rather than global severity averages alone. Methods This

Association between periodontitis and oral health–related quality of life in patients with systemic conditions: A meta‐analysis

Journal of Periodontology, EarlyView.
Abstract Background The objective of this systematic review is to evaluate whether periodontitis is associated with impaired oral health–related quality of life (OHRQoL) in adults with systemic conditions. Methods Five databases were searched to identify observational studies that tested the association between periodontitis (diagnosed by clinical ...

Periodontitis during pregnancy: The effect on the gut microbiome and intestinal inflammation

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis has been epidemiologically associated with adverse pregnancy outcomes, but causality remains difficult to establish in humans due to confounding factors. This study uses a controlled murine model to examine the effects of experimentally induced periodontitis on the composition of the gut microbiota and gastrointestinal
