Effectiveness of Procedural Video Versus Live Demonstrations in Teaching Laboratory Techniques to Dental Students.

Even though the traditional live demonstration method is commonly used in teaching laboratory techniques to dental students, it has many drawbacks. The aim of this study was to assess the acquisition of knowledge, practical skills, and perceptions of dental students who had a live demonstration versus procedural video on arranging artificial teeth. All 79 third-year dental students at a dental school in Sri Lanka, who had no previous experience in arrangement of teeth, were randomly divided into two groups in 2016.
