Oral health’s association with general health, morbidity, and mortality in older adults highlights its importance for healthy aging. Poor oral health is not an inevitable consequence of aging, and a proactive, multidisciplinary approach to early recognition and treatment of common pathologies increases the likelihood of maintaining good oral health. Some individuals may not have regular access to a dentist, and opportunities to improve oral health may be lost if health professionals fail to appreciate the importance of oral health on overall well-being and quality of life. The authors of this narrative review examined government websites, the American Dental Association Aging and Dental Health website, and the Healthy People 2030 oral objectives and identified xerostomia, edentulism, caries, periodontitis, and oral cancer as five key topics for the non-dental provider. These conditions are associated with nutritional deficiencies, poorer quality of life, increased risk of disease development and poorer outcomes for cardiovascular disease, diabetes, and other systemic conditions prevalent among older adults. It is important to note that there is a bi-directional dimension to oral health and chronic diseases, underscoring the value of a multidisciplinary approach to maintaining oral health in older adults.

Purpose/objectives Dental students’ levels of engagement and comprehension were assessed using tactile learning (with physical teeth) versus virtual learning (using computer images) in a dental histology course. Differences in engagement and comprehension by learning preferences were also examined. Methods One hundred first‐year dental students were randomly divided into twenty teams of five students. Conditions were counterbalanced such that half the students were given physical tooth models (Group A) while the other half were given access to virtual images of tooth models (Group B) during the first session. Conditions were switched for a second session. Both groups completed the same learning exercise and formative assessment (quiz) after each session. A survey assessed students’ learning preferences and attitudes. Results There were no differences by group assignment in both formative assessment scores and learning preferences ( p > 0.10). For all students, comprehension of material was significantly higher in the tactile condition (with physical teeth) compared to the virtual experience ( p = 0.01), but there was no difference in engagement between conditions ( p = 0.35). Students who preferred learning with physical tooth models had higher engagement when using the physical tooth models compared to those who preferred virtual tooth models ( p = 0.04), and significantly more positive attitudes toward physical tooth models ( p's < 0.0001). Conclusion Results suggest that for dental students, learning activities involving handling physical teeth may produce greater comprehension than viewing virtual images of teeth on a screen. More research is needed to determine the circumstances when virtual images can be substituted for physical models or be a beneficial adjunct method.
