Feedback and motor skill acquisition using a haptic dental simulator.

Area of Science:

• Dental Education
• Virtual Reality Simulation
• Haptic Technology

Background:

• Effective pedagogical feedback is crucial for acquiring manual dexterity skills in dentistry.
• Virtual reality (VR) haptic simulators offer a novel platform for dental skills training.
• Different feedback modalities may impact learning outcomes differently.

Purpose of the Study:

• To compare the effectiveness of device-only feedback (DFB), instructor feedback (IFB), and combined instructor and device feedback (IDFB) on dental skill acquisition.
• To evaluate the impact of feedback type on the transfer and retention of basic manual dexterity skills.
• To assess the role of VR haptic technology in dental education.

Main Methods:

• Sixty-three novice participants were randomly assigned to DFB, IFB, or IDFB groups.
• Training involved four tasks using a VR haptic dental simulator with group-specific feedback.
• Skills transfer and retention were assessed at multiple time points post-training.

Main Results:

• Statistically significant differences in overall performance and error rates were observed between groups (P < 0.001).
• The IDFB group demonstrated superior performance and fewer errors compared to DFB and IFB groups.
• Improved skill retention and generalization to novel tasks were noted in the IDFB group.

Conclusions:

• A combination of instructor and VR visual display feedback (IDFB) optimally enhances the acquisition and retention of basic dental motor skills in novice trainees.
• These findings support the integration of VR haptic technology and multimodal feedback in dental curricula.
• The study highlights the potential of IDFB for improving dental education outcomes.
