Males with an elevated DII score had 27.15 times higher odds of being diagnosed with gingivitis and BoP (<i>β</i> = 6.54; <i>p</i> = 0.03). Elderly patients with a moderate or high DII score were less prone to gingivitis and increased BoP (<i>p</i> &lt; 0.04) compared with younger subjects. Considering the DII, there were no differences in microbial alpha and beta diversity; however, distinct species abundance and a higher concentration of monocyte-chemoattractant protein-1 and interleukin 33 were seen in patients with a higher DII.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>A pro-inflammatory diet significantly contributes to periodontal inflammation, modulating inflammatory biomarkers and affecting the subgingival microbial community in healthy individuals.</p>\u0000 </section>\u0000 </div>","PeriodicalId":16716,"journal":{"name":"Journal of periodontology","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/JPER.23-0292","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139048927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
