Randomized Controlled Trial
The Effect of Magnification Loupes on Spontaneous Posture Change of Dental Students During Preclinical Restorative Training.
Scientific evidence validating the beneficial effect of loupes in preventing musculoskeletal disorders is very scarce. The aim of this study was to assess the impact of dental loupes on dental students' posture during a preclinical restorative dentistry course. Using a randomized crossover design, this study was conducted at the School of Dentistry, University of Nantes, France, in 2017. ⋯ Cavity preparations were not improved by the use of loupes. The questionnaire revealed negative aspects (pain and difficulty adapting) but underlined the perceived positive impact on posture. This study documented the ergonomic advantages and challenges of introducing magnification near the beginning of the dental training program.

The aim of this study was to evaluate the effectiveness of a mobile augmented reality simulator for local anesthesia training with dental students who are administering inferior alveolar nerve block (IANB) for the first time. Participants in this prospective study conducted in 2016 were 41 fourth- and fifth-year students randomly divided into two groups: a control group with 19 students and an experimental group with 22 students. In addition to theoretical instruction and exercises, students in the experimental group used the mobile augmented reality simulator in a dental office 2h weekly for four weeks. ⋯ In addition, the group that used the augmented reality simulator had an anesthesia success rate of 90.9% compared to 73.7% for the control group. Students in both groups had a statistically significant increase in heart rate while performing anesthesia. Overall, the students who used the mobile simulator in addition to their education in augmented reality carried out anesthetic procedures for IANB in a shorter period of time and had greater success than the students who used only the conventional educational methods.
