Participants receive individualized oral hygiene training using the Individually Trained Oral Prophylaxis (iTOP) method. The intervention is delivered in a one-to-one chairside session and uses the Touch-to-Teach technique, where the clinician guides the participant's hand to demonstrate correct toothbrushing and interdental cleaning movements. Calibrated interdental brushes are selected based on individual interdental space measurements using a color-coded interdental access probe. Participants practice the technique under supervision until proper technique is achieved. Reinforcement sessions are provided at 2 weeks, 1 month, and 3 months to ensure adherence and correct oral hygiene performance.

Participants receive conventional oral hygiene education consisting of verbal explanation, model demonstration, and video-based instruction illustrating standard toothbrushing and interdental cleaning techniques. This educational approach provides visual and verbal guidance but does not include individualized calibration of interdental brushes or hands-on correction of brushing technique. Participants are instructed to brush twice daily and perform interdental cleaning once daily using the provided oral hygiene kit. Reinforcement sessions using the same demonstration and video-based instruction are conducted at 2 weeks, 1 month, and 3 months.
