Behavioral Change Simulation Experiment Regarding Dentists' Repair Behavior

Not Applicable

Completed

• Conditions: Behavior
• Interventions: Other: Guideline; Other: Treatment fee item

• Registration Number: NCT05335616
• Lead Sponsor: University of Göttingen

Brief Summary

The aim of the present study is to determine the effect of two potential interventions on dentists' behavior regarding the repair of partially defective dental restorations.

Detailed Description

Two potential interventions are delivered as written instructions to the participants. Dentists are asked to indicate their treatment preference for two given clinical scenarios (consisting of case vignettes, clinical photos, and radiographs) in two questionnaires prior (baseline data) and after receiving the intervention. Based on these data, the simulated behavior change (i.e. to repair or not to repair) will be assessed.
