In fully adjusted models of 24 selected systemic comorbidities, the odds ratios (ORs) for severe periodontitis consistently exceeded those for mild\/moderate periodontitis. For instance, smoking showed ORs of 1.78 (mild\/moderate) versus 5.21 (severe), diabetes (2.20\u00a0vs. 5.59), cardiovascular disease (1.53\u00a0vs. 2.21), human immunodeficiency virus (HIV) (2.25\u00a0vs. 4.07), and Alzheimer's disease (1.84\u00a0vs. 3.20).

Using electronic health record data from over 260,000 adults treated at 9 U.S. dental schools, we investigated whether people with systemic diseases\u2014like diabetes, cardiovascular disease, or human immunodeficiency virus (HIV)\u2014were more likely to have mild or severe periodontitis. The results showed that several conditions significantly increased the odds of having more severe gum disease. For instance, individuals with diabetes or cardiovascular problems had more than double the risk of severe periodontitis, while those with HIV or dementia showed even stronger associations. Some conditions, such as asthma or anorexia, were linked to lower odds of gum disease, suggesting that these relationships may be complex and deserve further study. Although this study cannot determine cause and effect, it highlights a pattern: people with chronic diseases are more likely to have more severe gum problems. This emphasizes the need for medical and dental care providers to work together when managing patients with chronic health issues, and it reinforces the importance of oral health as a part of overall well\u2010being.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jper.25-0055","type":"journal-article","created":{"date-parts":[[2025,8,8]],"date-time":"2025-08-08T10:08:56Z","timestamp":1754647736000},"page":"297-312","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Dose\u2010dependent association of systemic comorbidities with periodontitis severity: A large population cross\u2010sectional study"],"prefix":"10.1002","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5067-7317","authenticated-orcid":false,"given":"Muhammad H.
