Challenges to conducting research on oral health with older adults living in long-term care facilities.

Background: The challenges to conducting oral health studies involving older people in long-term care facilities (LTCFs) must be debated.

Objective: This study aimed to investigate researchers' perceptions and experiences while conducting an epidemiological survey on oral health among older individuals residing in LTCFs.

Methods: A qualitative study was conducted involving six researchers who utilized field diaries to record their impressions during data collection through interviews (older individuals (or their proxies), caregivers, and LTCF coordinators) and oral examinations of the older people participants.
