Applicability of both dentist and patient perceptions of dentists' explanations to the evaluation of dentist-patient communication.

OBJECTIVES: Very little is known about dentist-patient communicative behaviours in actual practice. This study evaluated dentist and patient perceptions of dentist-patient communication and patient outcome. PARTICIPANTS: The subjects were 171 dentist-patient pairs in Kitakyushu, Japan. RESEARCH
DESIGN: Dentists and patients answered the same questionnaire items using the same response categories to evaluate dentist-patient communication. Based on the scores of patient and dentist perceptions with respect to dentist-patient communication, patient-dentist pairs were categorised into one of 3 groups. Data analyses used one-way ANOVA, multiple linear regression analysis, and multiple logistic regression analysis.
RESULTS: We found that, with respect to dentist-patient communication, patients in the 'patient better' group (i.e., the patient's evaluation was more positive than the dentist's evaluation) were more likely to have a positive outcome (e.g., 'improvement of health and fear,' 'satisfaction with care') than those in the other two groups. Patients in the 'doctor better' group (i.e., the dentist's evaluation was the more positive) were more likely to have a negative outcome than those in the other two groups.
CONCLUSIONS: A positive patient outcome is more likely when the patient's evaluation is better than a dentist's evaluation with respect to dentist-patient communicative behaviours. The method based on patient and dentist perceptions with respect to dentist-patient communication might be effective in evaluating dentist-patient communication.
