Calculation of Meshing Backlash for Cycloidal-pin Gear of RV Reducer Under the Influence of Tooth Profile Deviation

Jixie chuandong, 2019
The meshing backlash of cycloidal-pin gear has a great influence on the meshing transmission performance and motion accuracy of RV reducer, so the accurate calculation of meshing backlash is an important content in the study of contact characteristics of

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.

Association of periodontitis with incidence of metabolic syndrome in Korea: A retrospective cohort study

Journal of Periodontology, EarlyView.
Abstract Background Although periodontitis has been linked to systemic conditions such as metabolic syndrome, longitudinal evidence remains limited. This nationwide population‐based cohort study aimed to investigate whether periodontal status is associated with the incidence of metabolic syndrome in Korea.

Severity of periodontitis and risk of ischemic stroke: A systematic review and meta‐analysis

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis is a prevalent chronic inflammatory disease with a systemic inflammatory burden and is implicated with vascular pathology. This systematic review and meta‐analysis evaluates the association between varying severities of periodontitis and ischemic stroke with various diagnostic criteria.
