A study of dentists' explanations and patient-dentist communication among older adults in Japan

In recent years, the proportion of elderly people in the total patient population has been increasing owing to the rapid aging of Japanese society. However, little is known about the age-specific healthcare communication challenges within the field of dentistry. Therefore, this study aimed to examine the relationship between dentists' explanations and patient-dentist communication among elderly patients.

The study included 146 dentist-elderly patient pairs from Fukuoka Prefecture, Japan. A questionnaire was administered to pairs of dentists and patients. The survey was conducted between June 2021 and April 2022. We examined the relationships among the survey items: dentist demographics, patient demographics and sufficiency of the dentist explanations, and patient-dentist communication. The logistic regression analysis was conducted to examine the patient's mode of visiting the dentist as the objective variable, sufficiency of the dentist explanations, patient-dentist communication, dentist, and patient factors as explanatory variables.

About 30% of patients felt that explanations of "Comparison with other treatment methods," "Treatment period," and "Treatment prognosis" were not sufficient. Among these items, a significantly higher percentage of respondents found the dentist's explanations sufficient when they were treated by more than one dentist. Many good communication factors were significantly associated with the dentist being younger and having a preventive practice. Multivariate analysis revealed a significant association between sufficiency of the dentist explanations and patients' regular dental visits.

Adequate explanations by dentists for elderly patients were significantly associated with the dentist factor. Improving the quantity and quality of the dentists' explanations of treatment may improve patient satisfaction and promote regular dental visits.
