About this study
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GuidelineOther
Hypothetical guideline regarding the indications and treatment steps involved in dental restoration repair.
Treatment fee itemOther
Arrangement of a hypothetical treatment fee item which can be charged in addition to the actual repair restoration.
| Study group | Role | What they receive |
|---|---|---|
| Intervention "Guideline" | Experimental | Participants are given written information (a hypothetical new guideline). Receives: Other: Guideline |
| Intervention "Treatment fee item" | Experimental | Participants are given written information about a hypothetical new treatment fee item. Receives: Other: Treatment fee item |
What is being measured
The primary outcome is the main question the study is designed to answer.
Simulated behavior change
Simulated behavior change, indicated by the proportion of dentists selecting repairs as their treatment preference for the given clinical scenarios.
Measured: 10 Minutes

Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05335616, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Feb 2024.
