NCT06877117

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.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Behavioral Change

    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.
