3.2. Student Perceptions
A questionnaire (Student responses to the open-ended questions suggested that the main benefits of training on the HVRS device was that it allowed more repetitions for practice and provided better visualization of pulp chamber and root orifices. Among the HVRS limitations was the lack of finger rests and the lag in navigating through the displayed images while performing the procedure. Most of the students also preferred to experience the HVRS training after the conventional simulation training. Student recommendations for improving pre-clinical training for the primary molar pulpotomy procedure included providing them an opportunity to practice the procedure on extracted primary teeth and scheduling extra pre-clinical sessions.
