Objectives: Family caregivers play an important role in maintaining the oral health of homebound older adults. Thus, this preliminary study investigated family caregivers' burdens and the oral care they provide to homebound older patients. Methods: A cross‐sectional survey was conducted. A questionnaire was distributed to 230 family caregivers of homebound older patients. We used the Japanese version of the Zarit Burden Interview (J‐ZBI) to measure caregiver burden. The cut‐off score for the J‐ZBI was 21 points.
