In this manuscript, the key assumptions required for MR analyses to yield credible causal inferences are reviewed. It is emphasized that even technically rigorous MR analyses may yield implausible conclusions if these assumptions are violated. The goal is to provide readers from nonstatistical backgrounds with a clear understanding of the foundational assumptions underpinning MR, complemented by a detailed discussion of specific considerations in oral health research, particularly when periodontitis is used as the exposure or outcome. As with any study design, MR is appropriate and can provide compelling evidence for causality in certain contexts, while its application may be unwarranted in others.

The bidirectional relationship between T2DM and periodontitis is well established, with poorly managed T2DM increasing the risk of inflammation, tissue damage, and dental implant failure. Advances in treatment, such as glucagon-like peptide 1 receptor agonists (GLP-1RAs), have led to better glycemic control and may reduce T2DM-related complications, highlighting their potential in addressing interconnected oral-systemic health challenges. This narrative review critically evaluates the literature on the impact of GLP-1RAs on periodontal and peri-implant health. 10 in vitro studies, nine preclinical animal studies, and one clinical study were explored to investigate their effects on periodontal regeneration, implant therapy, and related mechanisms. In vitro research revealed that GLP-1RAs, including exenatide and liraglutide, promoted osteogenic differentiation of periodontal ligament stem cells (PDLSCs) through pathways such as the mitogen Wnt/β-catenin and mitogen-activated protein kinase pathways, even in high glucose or inflammatory conditions. Synergistic effects with stromal cell-derived factor-1 further promoted PDLSC proliferation and bone regeneration. Animal studies demonstrated that GLP-1RAs mitigated periodontal inflammation, oxidative stress, and alveolar bone resorption while promoting bone remodeling and implant osseointegration, independently of glycemic control. Importantly, advanced delivery systems, such as exenatide-loaded chitosan-poly(lactic-coglycolic acid) microspheres, further increased peri-implant osseointegration in diabetic models. The sole clinical study, a retrospective cohort study, assessed peri-implant marginal bone loss in peri-implantitis patients treated with different hypoglycemic drugs. Results showed significantly less clinical and radiographic bone loss in the GLP-1RA group compared to insulin and metformin groups (p < 0.01). Overall, while GLP-1RAs have promising anti-inflammatory, osteoprotective, and pleiotropic properties, their role appears more aligned with preserving periodontal and peri-implant health in T2DM individuals than directly treating periodontitis or peri-implantitis. By delineating current evidence and research directions, this review calls for medical and dental professionals to collaborate in leveraging these novel treatment options in future studies to improve patient care and address the intricate challenges that diabetes presents to oral health.</p>","PeriodicalId":16715,"journal":{"name":"Journal of periodontal research","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144031112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, they can serve as a significant source of data for systematic reviews. However, specific considerations are necessary when evaluating the risk of bias (RoB) of cross-sectional studies, as several potential biases can undermine the validity, reliability, and robustness of their findings. This article introduces a novel, context-specific tool designed to assess the RoB of cross-sectional studies for use in systematic reviews. The proposed tool represents an adaptation of the Newcastle-Ottawa Scale (NOS), originally developed for cohort and case-control studies. Similar to the original NOS, the new tool (named \"NOS-xs\") features a nine-star rating system to assess six specific items across three main domains: (i) study sample selection, (ii) assessment of exposure(s) and outcome(s), and (iii) confounding factors. Based on the number of awarded stars, studies are categorized as having high (0-3 stars), moderate (4-6 stars), or low (7-9 stars) RoB. The NOS-xs tool maintains consistency with the original NOS tool, facilitating its integration into systematic reviews that also include cohort and/or case-control studies. While the NOS-xs is suited to analytical cross-sectional studies (i.e., association studies), a simplified version (\"NOS-xs2\") is also introduced for descriptive cross-sectional studies (i.e., prevalence studies). The NOS-xs2 features a four-star rating system to assess three of the six specific items included in the NOS-xs. To streamline their application, spreadsheets for both NOS-xs and NOS-x2 are provided.</p>","PeriodicalId":16715,"journal":{"name":"Journal of periodontal research","volume":" ","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144012649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
