ABSTRACT
STATEMENT OF PROBLEM: Mainly because of poor training, substandard impression disinfection practices have been reported worldwide. PURPOSE: The purpose of this cross-sectional study was to assess the extension, usefulness, and reliability of contents on this topic available on the main video websites for self-training. MATERIAL AND METHODS: An analysis of the YouTube, Vimeo, and Dailymotion websites was undertaken in February 2018. The exclusion criteria were animal procedures, non-English language videos, advertisements, videos exclusively redirecting to websites, soundless videos, duplicated videos, and videos reporting on a research project. Information extension was assessed in 6 nonmutually exclusive dimensions, and usefulness was evaluated by using a 10-item scale. Reliability was assessed on a reliable or nonreliable basis. Statistical analyses were undertaken by using the Mann-Whitney and Fisher exact tests. RESULTS: Of 386 identified videos, only 22 met the selection criteria, mostly published by health-care professionals (n=8; 36.4%). Most videos had less than 3000 views. Median usefulness score: 3 (IR: 3-3; range: 0-6). No video included all 7 topics considered in the index (median 3; IR: 2.25-3; range: 0-4). Just 5 clips (22.7%) described a procedure according to the American Dental Association and Center for Disease Control (ADA and CDC) guidelines. CONCLUSIONS: Audiovisual online resources on dental impression disinfection includes incomplete information with limited usefulness and reliability. The number of views was not related to quality, and therefore, many viewers may be obtaining knowledge from substandard material.

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.
