About this study
This study aims to determine the association between race and clinical decision-making for dental treatment planning. The investigators conducted cross-sectional survey on participants, who are randomized to one of two patient race conditions.
Read the detailed description
The study is a randomized cross-sectional survey which is marketed as an exploration of tooth restorability. The condition of randomization is patient race. Dentist participants are randomized to a patient (either Black or White race) and provided with a clinical vignette. The participants are asked to review the clinical vignette and provide their treatment recommendation. Then, they answer questions on dentist and patient demographics. Next, they complete two Implicit Association Tests related to race and dentistry. Finally, the participants are given a debrief of the true purpose of the study. The survey is completed in one sitting.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Black Patient race conditionOther
The participants who are randomized to this group will be assigned the Black patient.
White Patient race conditionOther
The participants who are randomized to this group will be assigned the White patient.
| Study group | Role | What they receive |
|---|---|---|
| Black Patient race condition | Other | Not described Receives: Other: Black Patient race condition |
| White Patient race condition | Other | Not described Receives: Other: White Patient race condition |
What is being measured
The primary outcome is the main question the study is designed to answer.
Treatment Decision
The participants answer a survey question asking if they would recommend a Root Canal Treatment or Tooth Extraction for the patient. The survey does not require a follow-up, so the outcome is measured when the participant completes the survey in one sitting.
Measured: Day 1 (Day of survey start and completion)
Secondary outcomes (1)
Implicit Association Test Score
The Implicit Association Test is a validated socio-cognitive test. The score ranges from -1 to 1. The survey does not require a follow-up, so the outcome is measured when the participant completes the survey in one sitting.
Measured: Day 1 (Day of survey start and completion)
