Oral Health Literacy Levels of Nursing Professionals and Effectiveness of Integrating Oral Health Training into Nursing Curricula: A Systematic Review

This systematic review assessed the evidence for the oral health literacy levels (i.e., knowledge, attitudes, barriers, oral care and practices, and trainings and resources) of nursing professionals and the effectiveness of integrating oral health training into nursing training. Four electronic databases were searched; however, for relevance, only evidence published between 2013 and 2023 was considered. Overall, 70 studies that focused on five key themes, namely, (i) knowledge of oral healthcare among nurses; (ii) attitudes of nurses towards oral healthcare; (iii) barriers to oral healthcare promotion; (iv) oral care and practices; and (v) trainings and resources to promote oral healthcare, were retrieved. Nurses were found to have a lack of or suboptimal of knowledge regarding oral healthcare. Moreover, their attitudes and practices related to the provision of oral healthcare varied substantially. Key barriers that impeded oral healthcare promotion included a lack of knowledge, awareness, education, skills, and training. Integrating oral health training was considered effective for improving oral health literacy and nurses emphasized the inclusion of such training into their curricula for improving oral healthcare. In summary, nurses have an important role to play in promoting oral health. Furthermore, integration of oral health training into nursing curricula could be a feasible approach to improve the oral health literacy of nurses and reduce the burden of oral disease.
