Abstract

Purpose: Performing restorative procedures is one of the scopes of practice for dental hygienists in Washington State. To ensure dental hygiene students are clinically competent with their skills upon graduation, remediation is inevitable. However, with current challenges faculty face with traditional remedial interventions such as heavy workload and faculty availability, an alternative effective method of providing restorative remediation for dental hygiene students would be beneficial. This study investigated whether the use of instructional videos in remediation enhanced dental hygiene students’ restorative skills. Methods: This mixed-method study used a convenience sample of senior dental hygiene students. In this counterbalanced experimental design, students were randomly assigned to two groups. Each group watched the videos in different orders. Group 1 watched the videos in the order of A-B, and Group 2 watched the videos in the order B-A. Quantitative data from pre-test and post-test timed carving scores were collected. Students were required to self-evaluate their own timed carvings before turning them in using the WREB carving grading rubric. Qualitative data were gathered using open-ended questionnaires. Results: Study results indicate an increase in students’ self-evaluation skills after watching the instructional videos. There were 36.2%, 12.5% and 6.3% increase in the percentage of agreement on Occlusal, Proximal and Margins criteria, respectively in Group 2 students and 20.1%, 0% and 6.7% increase in the percentage of agreement on Occlusal, Proximal and Margins criteria, respectively in Group 1 students. Although significant improvement in students’ restorative performance subsequent to the instructional videos exposure was not detected (p > .05), there were less failures after the exposure to both videos in both groups. Additionally, results show a direct correlation between students’ self-evaluation skills and restorative skills. Finally, data reveals students’ positive perception towards the use of the instructional videos in restorative laboratory. Conclusion: In order to serve the community safely, competency upon graduation is a must. It is the responsibility of educators to provide appropriate means and support to ensure student success. Instructional videos may be used as a helpful alternative remedial intervention in providing restorative remediation for dental hygiene students who struggle with poor performance.
