Addressing gaps in transversal educational contents in undergraduate dental education. The audio-visual 'pill of knowledge' approach.

ABSTRACT

INTRODUCTION: Training on impression disinfection is often limited to brief explanations in the clinic. This investigation assessed knowledge on this topic amongst clinical students in our university, produced a pill of knowledge to suit their needs, and evaluated its impact and acceptance. MATERIAL AND METHODS: A pre-post study was designed to identify knowledge gaps using an anonymous, voluntary self-applied questionnaire before and after watching an audio-visual clip (pill of knowledge). All 136 students in the school were invited to enter the study (estimated sample size 116). RESULTS: Participants: 109 (26.6% in 3rd year; 37.6% in 4th year and 39.4% in 5th year). Participation dropped 10.29% (n = 95) in the post-intervention survey. Knowledge improvement was higher for those impression materials included in the pill. Most students (68.4%) reported to know more about impression disinfection after the pill and 70.5% felt more able to achieve correct disinfection. The pill was particularly well received (86.3%). All students would recommend it to their peers, and 93.5% are willing to receive pills on other topics. DISCUSSION: Our results disclosed an important gap in knowledge, which can be filled by a single, brief and concise pill adapted to the intended audience. Once made readily available through digital repositories, it may help solve this problem, given the ubiquitous presence of mobile devices. CONCLUSIONS: Our results found pills of knowledge as a useful approach to facilitating undergraduates' learning process. This method, using suitable information and communication technologies, has the potential to improve the performance on certain clinical tasks.
