Effectiveness of Personalized Oral Hygiene Education in Medical and Dental Students Over Two Years

The iTOP intervention consists of a single, structured, 45-minute, small-group oral hygiene training session conducted by certified dental professional. The session includes personalized instruction on proper toothbrushing techniques (e.g., Bass technique), use of interdental brushes and floss, and patient motivation. At the 3-month follow-up, participants also received a short reinforcement session. Standardized oral hygiene kits (toothbrush, interdental brushes) were provided at each time point.
