BACKGROUND AND OBJECTIVES: Older adults report unmet oral health care needs and barriers in access to care, due in part to provider attitudes and discomfort towards treating older patients. Our study asked: What is known from the literature about the use of undergraduate dentistry programmes to influence dental students' attitudes, perceptions and comfort towards treating geriatric patients? And how can interdisciplinary care facilitate the ability of dentists to work with geriatric patients? MATERIALS AND METHODS: A scoping review and stakeholder consultation followed established methodological guidelines. Four databases and two grey literature sources were searched. Two researchers independently selected articles using predefined inclusion criteria. Pertinent information was inputted into an iteratively developed extraction table. NVivo 12 was used to organise the extracted data into themes. Key findings were confirmed through stakeholder consultation. RESULTS: Sixty-eight articles were included in the scoping review. Five key themes emerged: (1) Curricular targets
(2) Intervention components
(3) Dentist and patient factors
(4) The role of interdisciplinary care
and (5) Post-graduation insights on knowledge-seeking patterns. Stakeholder consultations involved 19 participants from Southwestern Ontario and generally confirmed our findings. CONCLUSIONS: Inconsistent reporting of multiple intervention dimensions constrains our ability to strengthen this knowledge. Future interventions and their reporting could be improved by adopting "willingness to treat" as an overarching, multi-faceted concept which encompasses knowledge on ageing, attitudes towards older patients, perceived competence and empathy. Stakeholder interviews complemented these findings.
