The hypothesis is that this integrated approach will lead to better acquisition of practical skills.\n\nThe study is designed as a prospective, randomized controlled trial. Forty dental students about to begin their clinical internship will be randomly assigned to one of two groups. One group will receive traditional teaching involving lectures and instructor-led demonstrations on dental simulators. The other group will receive the experimental intervention, which combines the use of a virtual simulation training module with video recording of hands-on practice sessions. In the experimental group, students will review their recorded performances for self and peer assessment under instructor guidance.\n\nAll participants' ceramic veneer preparation skills will be assessed before the training begins. Their skills will then be re-evaluated at 1 month, 2 months, and 3 months after completing the training. The assessments will focus on two main areas: the ergonomic quality of the student's operating posture and the technical quality of the tooth preparation they perform on a simulator."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '21 Years', 'minimumAge': '17 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Prospective dental students from Jiangsu Medical College who were about to start clinical internships.\n* Students who have completed theoretical and practical coursework in the dental profession.\n* Students who are about to undergo pre-service training for clinical placements.\n\nExclusion Criteria:\n\n* Not applicable'}, 'identificationModule': {'nctId': 'NCT07398794', 'briefTitle': 'Video Feedback Teaching With Virtual Simulation', 'organization': {'class': 'OTHER', 'fullName': 'Jiangsu Medical College'}, 'officialTitle': 'Evaluation of Combining Video Feedback Teaching With Virtual Simulation for Ceramic Veneer Tooth Preparation: A Prospective Randomized Controlled Study', 'orgStudyIdInfo': {'id': 'JiangsuMC'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Traditional Teaching', 'description': 'This group received the traditional teaching method.
