Plain English Summary

Background and study aims
Bias is an inclination for or against a person or a group, as it allows for one's personal opinions to influence judgement. It is defined in the Oxford dictionary as an ‘inclination or prejudice, for or against one person or group, especially in a way considered unfair.’ There are many forms of bias, which are generally one sided and have the ability to affect everyday social interactions. The aims of this study are to determine whether explicit and implicit racial bias predicts the recommendation of root canal therapy or extraction for White and Black patients suffering from irreversible pulpitis (inflammation of dental pulp tissue), and to determine whether different treatment decisions are made for Black vs White patients and to determine whether such differences (if any) are related to the presence of explicit or implicit racial bias.

Who can participate?
Qualified dentists

What does the study involve?
Participating dentists are given a clinical scenario in combination with a patient’s relevant clinical photographs and radiographs depicting either a Black or White patient presenting with a decayed tooth and the associated symptoms of irreversible pulpitis. Explicit bias is measured through a questionnaire, which evaluates the recommended course of treatment, the strength of the recommendation and their perception of the patient’s dental cooperativeness. Implicit bias is evaluated through brief implicit association tests.

What are the possible benefits and risks of participating?
The possible benefits are to create early awareness and active prevention. Although it might not be likely to completely eliminate the effects impact biases can have upon decision making, a reduction in the occurrence is a worthy result. Ultimately by creating awareness, bias can be recognised and reduced. The risks of participation are that during the tests participants may feel uncomfortable and may not want to continue further.

Where is the study run from?
The University of Cagliari (Italy)

When is the study starting and how long is it expected to run for?

Condition

Implicit and explicit bias and its influence on clinical treatment planning decisions

Intervention

Dentists were given a clinical scenario in combination with a patient’s relevant clinical photographs and radiographs depicting either a Black or White patient presenting with a decayed tooth and associated symptoms of irreversible pulpitis.

Explicit bias was measured through a questionnaire, which evaluated participants’ course of treatment, strength of recommendation and their perception of patient’s dental cooperativeness.

Implicit bias was evaluated through brief implicit association tests.
