Objective: The objective of this study was to summarize and compare the local and systemic impact of different models of experimental periodontitis in mice.
Design: After defining the PICO strategy, was performed a search for articles in English following the PRISMA guidelines in PubMed, Embase, Scopus, Web of Science, Cochrane and LILACS databases. The search strategy provided 8815 articles from which were selected experimental studies comparing the local and/or systemic effects of two or more models for the induction of periodontitis in mice according to the inclusion and exclusion criteria.
Results: After selection, 7 articles that met the inclusion criteria for the review. Were analyzed differences between the following experimental models of periodontitis in mice: ligature, gavage, injection of bacteria, ligation embedded in bacteria and association between them.
Conclusion: Although most experimental models of periodontitis are efficient in causing alveolar bone loss, there are differences in their characteristics. In ligature, an acute process is established and the host tends to repair itself, decreasing the significance of this loss over time. In models where bacterial challenge is added bone loss appears to be significant with longer induction time, indicating the presence of a chronic condition. Regarding systemic outcomes, gavage showed greater potential for modulating the host's response with systemic inflammatory changes, proving to be more promising between periodontitis and chronic systemic diseases.

Unlabelled: Periodontitis (PD) is a polymicrobial dysbiotic immuno-inflammatory disease. Toll-like receptors (TLRs) are present on gingival epithelial cells and recognize pathogen-associated molecular patterns (PAMPs) on pathogenic bacteria, induce the secretion of proinflammatory cytokines, and initiate innate and adaptive antigen-specific immune responses to eradicate the invading microbes. Since PD is a chronic inflammatory disease, TLR2/TLR4 plays a vital role in disease pathogenesis and maintaining the periodontium during health.

Unlabelled: Periodontitis is closely related to renal health, but the specific influence of (), a key pathogen in periodontitis, on the development of acute kidney injury (AKI) in mice has not been fully elucidated. In our study, AKI was induced in mice through ischemia-reperfusion injury while administering oral infection with . Comprehensive analyses were conducted, including 16S rRNA sequencing, liquid chromatography-mass spectrometry (LC-MS) metabolomics, and transcriptome sequencing.

Osteoarthritis (OA) is a joint disease characterized by articular cartilage degradation. Persistent low-grade inflammation defines OA pathogenesis, with crucial involvement of pro-inflammatory M1-like macrophages. While mesenchymal stromal cells (MSC) and their small extracellular vesicles (sEV) hold promise for OA treatment, achieving consistent clinical-grade sEV products remains a significant challenge.

Periodontitis is the sixth most common disease worldwide and is closely associated with various systemic diseases, impacting overall health. It is characterized by the over-differentiation and activity of osteoclasts, leading to increased bone resorption and subsequent bone loss. Current treatments for bone loss are not ideal, highlighting the need for new targeted therapeutic strategies.

Cellular senescence has emerged as one of the central hallmarks of aging and drivers of chronic comorbidities, including periodontal diseases. Senescence can also occur in younger tissues and instigate metabolic alterations and dysfunction, culminating in accelerated aging and pathological consequences. Senotherapeutics, such as the combination of dasatinib and quercetin (DQ), are being increasingly used to improve the clinical outcomes of chronic disorders and promote a healthy life span through the reduction of senescent cell burden and senescence-associated secretory phenotype (SASP).
