Background: Virtual simulation via haptic feedback could be a good approach to get a lot of preclinical experience for dental students in a fast and efficient way. This study aimed to evaluate and compare the crown preparation by third year dental students via virtual reality and the same done in a conventional training environment on typodont teeth.
Materials and methods: 24 second-year dental students of the Saveetha Dental College and Hospitals, Chennai were enrolled and randomly defined. Group A (n=12) included crown preparations on Virteasy haptic simulator, and group B (n=12) included conventional crown preparation on typodont teeth (Nissin Dental Products, India). The students performed four crown preparations and each crown preparation was graded by the same teacher. Statistical analysis was done using independent t-test.
Result: The 1st tooth preparation of both the groups showed no statistical difference (p>.05), but all the subsequent tooth preparations of Group B were significantly better (p<.05) than those of Group A.
Conclusion: Haptic simulation is an effective tool in teaching crown preparation to pre doctoral dental students and can provide better training as compared to conventional crown preparation on typodont teeth.
