Introduction: This review aimed to evaluate the perceived barriers, knowledge, and training, of different health care professionals in relation to the oral health of dependent people in nursing homes and access, as well, how this data was evaluated. Methods: Three electronic databases -PubMed/MEDLINE, Web of Science, and LILACS -were searched independently by two researchers for relevant studies published up to December 2023. Articles were selected according to the established inclusion and exclusion criteria, and a total of 35 studies were included. Results: Findings from the Nursing Dental Coping Belief Scale studies revealed disparities between training and daily oral health care, with experienced nurses experiencing challenges. Barriers described were categorized and included resident-related issues, organizational challenges, and caregiver-related difficulties. Most caregivers reported inadequate training, often informal or experiential, although they are involved in the hygiene of the elderly, with tooth brushing and denture cleaning being the most common practices. Low oral health literacy coexisted with recognition of the importance of oral health care. Conclusions: The findings advocate for targeted interventions, standardized training, and improved support systems to improve oral health care for the elderly in diverse health care settings.
