Study Overview
Brief Summary
This project aims to investigate whether simple behavioural interventions, such as pictorial framing and traffic-light-color-coding, can positively influence pediatric dentists' decision-making in adopting rectangular collimation over round collimation for dental radiographs taken in clinical practice.
Detailed Description
- Introduction Dental radiographs are essential in diagnosing oral conditions in pediatric patients. Despite the availability of rectangular collimation as a recommended radiation safety measure, many pediatric dentists continue to use round collimation, which results in unnecessary radiation exposure. This study explores whether nudging strategies-such as pictorial framing and traffic-light color coding-can influence pediatric dentists' decision-making to encourage the adoption of rectangular collimation.
- Research Objectives
This study aims to:
Educate pediatric dentists on the benefits of rectangular collimation over round collimation.
Assess current collimation practices among pediatric dentists. Evaluate whether behavioral nudging strategies influence pediatric dentists' willingness to adopt rectangular collimation. 3. Study Hypothesis Null Hypothesis: Nudging strategies (pictorial framing and traffic-light color coding) have no impact on pediatric dentists' willingness to adopt rectangular collimation.
Alternative Hypothesis: The implementation of nudging strategies positively influences pediatric dentists to use rectangular collimation. 4. Methodology Study Design

Outcomes
Primary Outcomes
Behavioral Change
Time Frame: Day 1
The primary outcome of this study is the change in pediatric dentists' reported willingness to adopt rectangular collimation based on the nudging strategies employed. Specifically, the study will measure whether pictorial framing and traffic-light-color-coding influence the likelihood of adopting rectangular collimation in clinical practice. Responses collected in 10 point visual analog scale will be compared for effectiveness of each nudging strategy individually in promoting behavior change and mean scores will be compared across all groups.
