Individual selection of interdental brushes using a web service

The aim of the study was to evaluate the clinical effectiveness of the INTERDENTALBRUSHES.ONLINE web service for individual selection of interdental brushes in patients with chronic periodontitis. Materials and methods. The randomized controlled trial included 42 patients with mild to moderate chronic periodontitis aged 35 to 65 years, divided into 4 groups: I — individually selected interdental brushes using the web service (n=12); II — self-selected brushes (n=10); III — without using brushes, only toothbrush, floss, and irrigator (n=10); IV — individually selected brushes using traditional paper-based recommendations (n=10). Brush selection was carried out using an IAP (Interdental Access Probe) with color coding. Clinical effectiveness was assessed using OHI-S, Mühlemann, and Russell indices at 2 weeks, 1 and 3 months after starting the study. Time spent on brush selection and patient adherence to recommendations were also evaluated. Results. After 3 months, Group I showed a statistically significant reduction in all indices compared to other groups: OHI-S from 2.5±0.3 to 0.5±0.2, Mühlemann index from 2.1±0.8 to 0.4±0.1, and Russell index from 4.5±0.9 to 1.2±0.3 (p<0.001). The use of the web service reduced brush selection time from 7.6±1.2 to 3.1±0.7 minutes (p<0.001) and increased patient adherence to recommendations to 83% versus 60% when using traditional paper-based recommendations (p<0.05). Conclusion. The use of a web service for individual selection of interdental brushes significantly improves the effectiveness of therapeutic and preventive measures in patients with chronic periodontitis by reducing the time spent on selecting hygiene products, increasing patient adherence to recommendations, and improving clinical indicators of periodontal tissue health.
