Comparison of the Effectiveness of Different Oral Hygiene Education Methods in Periodontal Treatment: A Randomized Controlled Study

Objective: The aim of this study was to evaluate and compare the clinical effectiveness of three different oral hygiene education methods (video, brochure and model demonstration) in removing microbial dental plaque and maintaining periodontal health after periodontal treatment. Materials and Method: A total of 210 patients (105 with gingivitis and 105 with periodontitis) aged 18-60 were included in this randomized controlled study. Participants were randomly divided into three groups (n=70): Group A (Video education), Group B (Brochure education) and Group C (Model demonstration). All patients received Phase 1 periodontal therapy. Clinical parameters including Plaque Index (PI), Gingival Index (GI), Probing Pocket Depth (PPD), Clinical Attachment Level (CAL) and Bleeding on Probing (BOP) were recorded at baseline (T0), 1 week (T1) and 8 weeks (T2) post-treatment. Statistical analysis was performed using SPSS 22.0 (p
