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.

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.

ANALYSIS OF TOоTH PROFILE AND MESHING CHARACTERISTICS OF DOUBLE CYCLOID PIN GEAR TRANSMISSION

Jixie qiangdu
The double cycloid tooth profile was applied to the NN type planetary gear transmission with small tooth difference. By analyzing the concavity, curvature and radius of curvature of the inner and outer cycloid tooth profile, the characteristics of the ...

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.

Association between xerostomia and peri‐implant health: A retrospective cohort study

Journal of Periodontology, EarlyView.
Abstract Background Dental implants are a long‐term and reliable solution to replace missing dentition, but subject to different patient‐related and biological changes that could alter its success. Xerostomia, or the alteration of the normal salivary flow, can impair oral function and potentially affect the success of any treatment, including implant ...

Mertk drives alveolar bone loss in experimental periodontitis associated with altered neutrophil function and osteoclast recruitment

Journal of Periodontology, EarlyView.
Abstract Background Alveolar bone loss is the hallmark of periodontitis and often remains refractory to conventional mechanical and antimicrobial therapies in chronic cases. Mer receptor tyrosine kinase (Mertk) has been implicated in bone homeostasis, yet the immune mechanisms by which Mertk modulates periodontal bone resorption remain insufficiently ...

Associated factors for mid‐buccal gingival recessions: Findings from the National Health and Nutrition Examination Survey

Journal of Periodontology, EarlyView.
Abstract Background Population‐level evidence on associated factors for mid‐buccal gingival recession (GR) severity stratified by periodontitis status remains limited. This study assessed the prevalence and severity of GR in United States (US) adults and identified associated factors.
