Evaluate the patterns of plaque development on fixed prosthetic restorations across distinct age cohorts to optimize preventive and maintenance strategies
Abstract
Purpose of the study: To investigate the formation mechanisms of dental plaque on fixed prosthetic constructions and assess the effectiveness of professional hygiene interventions for optimizing prevention and care.
Material and research methods: The study included 787 patients (787 prosthetic constructions) from the Department of Prosthetic Dentistry at the Non-State Educational Institution ‘Medical-Social Institute of Tajikistan’, Plaque was scored using the Prosthetic Plaque Index (PPI; 0–3 points). Statistical analysis included mean ± SE, percentages, and Student’s t-test (significance at p < 0.05). Patients were divided into five age cohorts: 20–29, 30–39, 40–49, 50–59, and ≥ 60 years.
Research results and discussion: Baseline PPI rose from 1.00 ± 0.63 in the 20–29 cohort to 2.50 ± 1.66 in those ≥ 60 years. After 90-day professional hygiene, mean PPI decreased to 0.00 (20–29), 0.40 (30–39), 0.30 (40–49), 1.00 (50–59), and 1.20 (≥ 60).
Conclusions: Regular professional cleaning every 90 days and tailored home-care protocols significantly reduce prosthetic plaque across all age groups—especially older patients—thereby prolonging prosthesis lifespan and reducing complication risk.
