Periodontal health metrics (PD, AL, SBI, PLI) and GCF inflammatory markers (TNF-α, IL-1β, IL-6, IL-8, hs-CRP, ICAM-1, HMGB1, PGE2) were markedly improved in the observation group, correlating with enhanced total effective rates (TER) for osteoporosis (95.0%) and periodontitis (91.7%) and a reduced adverse event rate (AER). The gene discussed is ICAM1; the disease is periodontitis.
