Objectives: The study of biological materials under a microscope is known as histology, which is one of the most challengingsubjects for students. Our objective was to develop a learning tool that can reduce the extrinsic load of studying histology andmake learning enjoyable and flexible. We used augmented reality (AR) to create a cellphone application called Dental AR. With Dental AR, students can use their cellphones as dynamic flashcards to hide or reveal the annotations of a histology slide. Our application enables students to study, practice, and self-test oral histology knowledge at their own pace. Methods: Weused Unity3D with Vuforia to develop Dental AR. To generate a set of target images, oral histology glass slides were scannedand converted to digital images. Annotated versions of the slides were used as output for the corresponding target images. Tounderstand user experiences and satisfaction with Dental AR, first-year dentistry students were invited to complete an onlinesurvey. Results: Dental AR was successfully developed and released on both the Apple and Google Play online app stores. The survey of dentistry students indicated overall satisfaction with Dental AR and willingness to use similar applications inother subjects. Conclusions: Dental AR can be used for in-class activities, gamification, and providing students with practicequestions to study and self-test outside the classroom. This application can be expanded in the future to incorporate moretarget images, videos, and interactive components to make learning histology less challenging and more enjoyable.
