Oral health care is essential, and digital training may influence healthcare professionals’ attitudes to and knowledge of oral health. The aim, therefore, was to evaluate the impact on attitudes to and knowledge of oral health after using a digital training module among Swedish healthcare professionals working within a municipality-run healthcare service for older adults. A secondary aim was to explore the healthcare professionals’ experiences of using the digital module.

The study comprised a survey of healthcare professionals (registered nurses (RNs), assistant nurses, and care assistants) caring for older adults in a municipality in Sweden. Pre-post-tests were conducted to evaluate the outcomes for attitudes to and knowledge of oral health and of their experiences of completing the digital training module in oral health. These were statistically explored by comparing differences between the pre-post-tests, while the open-ended questions were analysed with qualitative content analysis. The findings of this study indicate that healthcare professionals had similar perceptions of their attitudes to and knowledge of oral health both before and after the digital training module in oral health.

The study also indicates that healthcare professionals experienced that it is easier to perform practical oral health care after completing the digital training. The results also show that healthcare professionals value oral health knowledge and that the digital training module was easy to use and to disseminate knowledge throughout the municipality.

The findings have implications for developing, implementing, and promoting healthcare professionals’ attitudes to and knowledge of oral health and in using a digital training module in combination with practical exercises in oral health in municipality health care.
