The study will consist of a randomized pretest-posttest comparison group design. Study methodology will include comparison of baseline and exit surveys, multiple choice question pretest and posttest scores, and scores from diagnosis and treatment planning worksheets of two test cases. Student-teacher interactions will be recorded for types of interactions (technical, surgical prediction method, diagnosis, treatment planning, and other) and the length of interaction will be quantified. Data will be analyzed using descriptive statistics, and tested for evidence of significant association and/or correlation with each of the two educational intervention groups.
The objective of this study was to evaluate the feasibility of the testing methods and compare student understanding in diagnosing and treatment planning complex orthognathic cases using the VR Patient versus the 2D prediction tracing method.
This preliminary study explored the feasibility of the study methods and compared understanding of dental students in diagnosing and treatment planning of complex orthognathic cases using the VR Patient and traditional 2D tracing method. We found that student understanding improved immediately following the educational intervention; however, no significant difference was found between the two groups. There was a trend toward increase knowledge retention for the VR group but this was not statistically significant. This may be due to a small sample size. since concluding this study, we were able to introduce this educational tool in a graduate course, specifically, Ortho754 Orthognathic surgery to help graduate orthodontic residents to learn about jaw surgery prediction using VR.
There are multiple projects ongoing utilizing the VR workstations that has been funded by this grant. Also, we were able to receive further funding through Oculus Education Group using our preliminary study results.
The manuscript "A COMPARISON OF 2-DIMENSIONAL PREDICTION TRACING AND A VIRTUAL REALITY PATIENT METHOD FOR DIAGNOSIS AND TREATMENT PLANNING OF ORTHOGNATHIC CASES IN DENTAL STUDENTS: A RANDOMIZED PRELIMINARY STUDY" has been accepted for publication by Virtual Reality journal. Oral presentations were made at national meetings.
Advice to your Colleagues:
Getting the initial funding and using it in a way that was sustainable (obtain 3 VR workstations that could be used for other projects)helped to leverage the grant for more research opportunities.
