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

Impact of toothbrush type and periodontal phenotype on root coverage stability: A 6‐year observational follow‐up of a randomized clinical trial

Journal of Periodontology, EarlyView.
Abstract Background This 6‐year observational follow‐up of a randomized, parallel‐arm clinical trial evaluated the association between toothbrush type and periodontal phenotype on the long‐term stability of the gingival margin (GM) following coronally advanced flap (CAF) surgery.

Cycloid Gear Profile Modification based on Elliptical Method

Jixie chuandong, 2019
In order to get a more ideal cycloidal profile,a new cycloid profile modification method is proposed. Under the circumstance of keeping the short coefficient and the eccentricity constant,the contour line of the modified tooth profile is obtained by the ...

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.
