This study aims to compare the effectiveness of a mobile application versus the conventional tell-show-do (TSD) technique in reducing dental anxiety among children aged 7-11 years attending their first dental visit. The study is a multicenter randomized controlled trial conducted at tertiary care dental hospitals in Karachi, Pakistan. Participants are randomly assigned to either a mobile application-based behavioral intervention or the TSD technique prior to a dental diagnostic procedure. The primary outcomes include changes in pulse rate and anxiety levels measured using the Raghavendra Madhuri Sujata Pictorial Scale (RMS-PS) before and after the intervention. The findings of this study will help determine whether mobile-based behavioral tools can improve anxiety management in pediatric dental settings.
