Therefore, the aim of this pilot study was to evaluate, in a proof of concept, whether there is a correlation between the overall periodontal inflammatory surface area (PISA), periodontal clinical parameters (pocket probing depths (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), furcation involvement (FI), tooth mobility (TM)), and the dietary behavior of patients with periodontal disease when utilizing a practice-based research network. The primary outcome was the correlation between the periodontal inflammatory surface (PISA) and the dietary assessment data. Materials and Methods: The practice-based research network, consisting of eight Master\u2019s graduates, recruited patients who met the inclusion and exclusion criteria and performed a periodontal examination together with the assessment of dietary behavior using a digital version of the validated retrospective dietary recall (DEGS\/RKI). Statistical analyses included linear regression models adjusted for age and smoking and unpaired t-tests, conducted using STATA 17.0 with a significance level of 5%. In addition, the data obtained were classified according to the currently recommended amounts of daily intake. Results: A total of 1283 teeth were analyzed, with 60.25% (773 teeth) requiring treatment. The average PISA was 753.16 mm2 (SD \u00b1 535.75 mm). Based on dietary guidelines, the studied population consumed excessive amounts of extrinsic sugars and fats, while their fiber and legume intake was insufficient. The intake of certain nutrients, including water-soluble fibers, specific fatty acids, vitamins (D, B1, B2, B6, and B12), iron, and zinc, was associated with reduced PISA, PPD, CAL, and BOP. Conclusion: Within the limits of the current study, including its cross-sectional design and cohort size, the outcomes demonstrated the influence of nutrition on periodontal health.<\/jats:p>","DOI":"10.3390\/nu16183102","type":"journal-article","created":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T10:56:57Z","timestamp":1726484217000},"page":"3102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Nutrition and Periodontitis: A Cross-Sectional Study from a Practice-Based Research Network"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9121-4984","authenticated-orcid":false,"given":"Stefanie Anna","family":"Peikert","sequence":"first","affiliation":[{"name":"Department of Dental Medicine and Oral Health, Medical University of Graz, Billrothgasse 4, 8010 Graz, Austria"},{"name":"Department of Operative Dentistry and Periodontology, Faculty of Medicine, University of Freiburg, Hugstetter Stra\u00dfe 55, 79106 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-6780-4532","authenticated-orcid":false,"given":"Nils Benedikt","family":"Liedtke","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry and Periodontology, Faculty of Medicine, University of Freiburg, Hugstetter Stra\u00dfe 55, 79106 Freiburg, Germany"},{"name":"Section for Clinical Oral Microbiology, Department of Odontology, Faculty of Health and Medical Sciences, University of Copenhagen, N\u00f8rre All\u00e9 20, 2200 Copenhagen N, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9278-2203","authenticated-orcid":false,"given":"Kirstin","family":"Vach","sequence":"additional","affiliation":[{"name":"Institute of Medical Biometry and Statistics, Faculty of Medicine and Medical Center, University of Freiburg, Stefan-Meier-Stra\u00dfe 26, 79104 Freiburg im Breisgau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva","family":"Streletz","sequence":"additional","affiliation":[{"name":"Private Dental Practice Dr. Eva Streletz, 63150 Heusenstamm, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5471-3071","authenticated-orcid":false,"given":"Steffen","family":"Rieger","sequence":"additional","affiliation":[{"name":"Department of Operative Dentistry and Periodontology, Faculty of Medicine, University of Freiburg, Hugstetter Stra\u00dfe 55, 79106 Freiburg, Germany"},{"name":"Private Dental Practice Rieger Zahnmedizin, 72766 Reutlingen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia","family":"Palm","sequence":"additional","affiliation":[{"name":"Private Dental Practice Dentapaz, 74072 Heilbronn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Mittelhamm","sequence":"additional","affiliation":[{"name":"Private Dental Practice Dres.
