Why it matters for dental

Periodontal specialists and nursing-home dental teams should note that supra- and sub-gingival instrumentation measurably shifts the oral microbiome in elderly periodontitis patients, potentially altering infection risk and maintenance protocols in long-term care settings.

Key points

  • Secondary analysis of an RCT conducted in nursing-home residents aged ≥65 with periodontitis.
  • Both supra- and sub-gingival instrumentation produced measurable changes in microbial composition within 4–6 weeks post-treatment.
  • Findings are published in the Journal of Clinical Periodontology, EarlyView, and tagged for Academia and Specialist audiences.
  • Results may guide frequency and extent of instrumentation protocols for geriatric patients in residential care.
