The treatment, which involved cleaning and instrumentation below the gum line, was compared to no treatment. Thirty\u2010six participants (aged 85 years, on average) were included in the study. The results showed that after 3 months, the treatment group had a significant reduction in signs of gum inflammation (measured by bleeding on probing) and a decrease in the depth of the pockets around the teeth\u2014both indicators of gum disease. These improvements were not seen in the control group, which did not receive the treatment. The plaque levels in the mouth decreased slightly in the treatment group but did not show a strong difference compared to the control group. Overall, the findings suggest that even for older adults in nursing homes, a simple dental procedure to clean beneath the gums can improve gum health, reduce inflammation, and lower the risk of further gum disease. However, the improvements were modest, likely due to difficulties in maintaining adequate daily oral hygiene within this vulnerable population. This underscores both the importance of providing dental and periodontal care in nursing homes and the need for enhanced support with daily oral hygiene to achieve satisfactory outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/jper.70041","type":"journal-article","created":{"date-parts":[[2025,12,26]],"date-time":"2025-12-26T08:16:28Z","timestamp":1766736988000},"page":"1170-1182","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Shortened outreach periodontal therapy in nursing home residents with periodontitis: A randomized controlled trial"],"prefix":"10.1002","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0169-2582","authenticated-orcid":false,"given":"Anna G.","family":"Barbe","sequence":"first","affiliation":[{"name":"Polyclinic for Operative Dentistry and Periodontology Faculty of Medicine and University Hospital Cologne, University of Cologne  Cologne Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-5119-7291","authenticated-orcid":false,"given":"Dalia","family":"Beck","sequence":"additional","affiliation":[{"name":"Polyclinic for Operative Dentistry and Periodontology Faculty of Medicine and University Hospital Cologne, University of Cologne  Cologne Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5174-928X","authenticated-orcid":false,"given":"Martin","family":"Hellmich","sequence":"additional","affiliation":[{"name":"Institute of Medical Statistics and Computational Biology (IMSB) University of Cologne, Faculty of Medicine and University Hospital Cologne Faculty of Medicine and University Hospital Cologne, University of Cologne  K\u00f6ln Germany"},{"name":"Department of Medical Statistics University Medical Center G\u00f6ttingen, Georg\u2010August\u2010University  G\u00f6ttingen Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-7390-1557","authenticated-orcid":false,"given":"Max","family":"von Kohout","sequence":"additional","affiliation":[{"name":"Institute of Medical Statistics and Computational Biology (IMSB) University of Cologne, Faculty of Medicine and University Hospital Cologne Faculty of Medicine and University Hospital Cologne, University of Cologne  K\u00f6ln Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2239-6010","authenticated-orcid":false,"given":"Sonja H.
