Traditional manikin training has limitations that virtual reality can address. This study investigated the effectiveness of two part-task training simulation methods, a virtual reality (VR Sim) versus a plastic manikin (PM Sim), on learning outcomes for local anesthesia skills for second year pre-clinical dental students. In an experimental study, fifty-eight second year students were randomly assigned to one of two groups, VR Sim or PM Sim. Both groups completed the same pre-post survey. The VR Sim group practiced with a VR simulation, completed a built-in treatment test and a transfer test with a live person and evaluated by an expert teaching assistant (TA) with a rubric. The PM Sim group practiced with a plastic manikin, completed a treatment test on the same manikin evaluated by a TA, followed by the same transfer test with a live person and evaluated by a TA with a rubric. Covering knowledge and skills in the delivery of local anesthesia, mean final transfer test scores were statistically significantly higher for the PM Sim compared toVR Sim, F(1, 57) = 9.719, p = 0.003 with an effect size, η2p = .148. Scores on respective treatments tests were similar to final transfer test scores for each group suggesting differences were localized to the practice methods. Pre-survey results indicated participants had low prior experience with VR technology. While outcomes showed higher results for plastic manikin tutor training over the VR training method, they are complementary. As students practice more with the technology and the VR simulation they may improve further. Likewise, as the technology for haptics with VR improves beyond hand controllers so may the experience and learning of this skill for students.
