Effects of testosterone and high‐dose anabolic steroids on orthodontic‐induced bone remodeling and root resorption: An animal study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This study investigates the impact of disruptions in testosterone levels on bone remodeling, root resorption, and periodontal ligament (PDL) during orthodontic tooth movement (OTM) in a pubertal male rat model. Methods Testosterone deficiency was induced through orchiectomy, and the anabolic‐androgenic steroid (AAS, testosterone ...

Alterations in brain metabolites in rats with experimental periodontitis: A metabolomic approach

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Periodontitis (PD) is a chronic inflammatory disease with systemic effects. Emerging evidence suggests a link between periodontal inflammation and neurological changes, but the biochemical mechanisms in key brain regions, such as the hippocampus and amygdala, remain unclear.

Surveying immune and inflammatory alterations in periodontitis among individuals with Down syndrome: A preliminary cross‐sectional study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Individuals with Down syndrome (DS) are particularly vulnerable to early‐onset and rapidly progressing periodontitis, yet the local immune‐inflammatory alterations that contribute to this susceptibility are not fully understood. This study aimed to characterize cytokine profiles in gingival crevicular fluid (GCF) from individuals ...

Estradiol replacement attenuates alendronate‐associated adverse effects on alveolar bone repair in ovariectomized rats

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Sodium alendronate (ALN) is widely used to treat postmenopausal osteoporosis, but both estrogen deficiency and antiresorptive therapy may impair alveolar bone repair after tooth extraction. A clinically relevant but insufficiently explored scenario involves estrogen‐deficient individuals receiving hormone replacement therapy (HRT ...

Immunological and periodontal benefits of prebiotic polydextrose in rats with induced periodontitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Prebiotic therapy is a promising approach for managing periodontitis due to its potential benefits in modulating the microbiome and the immune response. This study aimed to evaluate the effects of the prebiotic (PREB) polydextrose (PDX) on the development of experimental periodontitis (EP) in rats.

Functional tooth unit, periodontal status, and association with weight change in older adults

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Literature reports that having fewer teeth is associated with reduced chewing capacity, which in turn may lead to weight changes due to diminished oral functionality. This study aims to assess the association between functional tooth units (FTU) and periodontal status and weight change among older adults participating in the Health,

Dasatinib and quercetin prevent alveolar bone loss in aged mice

open access: yesJournal 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.
