AIM: To determine the clinical association between periodontal disease and diabetes mellitus through an umbrella review. MATERIALS AND METHODS: A search for publications up to August 2023 was conducted using the following electronic databases: PubMed, Cochrane Database, Scopus, SciELO, Google Scholar, and OpenGrey. We included systematic reviews (SRs) with or without meta-analysis evaluating primary studies that investigated the association between periodontal disease and diabetes mellitus, and there were no time or language restrictions. Literature or narrative reviews, rapid reviews, intervention studies, observational studies, preclinical and basic research, abstracts, comments, case reports, protocols, personal opinions, letters, and posters were excluded. The AMSTAR-2 tool was used to determine the methodological quality of the included studies. RESULTS: The preliminary search yielded a total of 577 articles, of which only 17 remained after discarding those that did not meet the selection criteria. Following their analysis, an association between periodontal disease and diabetes mellitus (type 1 and type 2 diabetes mellitus and gestational diabetes mellitus) was found. CONCLUSIONS: The findings and conclusions of this umbrella review indicate with high confidence that periodontal disease is associated with the onset of type 1 and type 2 diabetes mellitus and gestational diabetes.
