Customized Virtual Simulation Platform for Practicing Root Canal Filling in Undergraduate Preclinical Course

Area of Science:

• Dental Education
• Simulation-Based Learning
• Endodontics

Background:

• Bridging theoretical knowledge and practical skills is crucial in dental education.
• Root canal filling requires precise theoretical understanding and hands-on proficiency.
• Virtual simulation offers a potential tool to enhance preclinical dental training.

Purpose of the Study:

• To evaluate if a virtual simulation platform for root canal filling aids students in transitioning from theory to practice.
• To assess the impact of virtual simulation timing on theoretical comprehension and practical performance.

Main Methods:

• Fourth-year dental students (n=126) were divided into pre-class and in-class virtual simulation groups.
• Theoretical tests assessed knowledge, and practical assignments evaluated root canal filling quality (length, density).
• Usage feedback and assignment grades were analyzed to compare groups based on virtual simulation timing.

Main Results:

• Virtual simulation timing did not significantly affect theoretical knowledge retention.
• Students using virtual simulation before practical sessions achieved higher grades in premolar filling quality.
• No significant differences were found in incisor filling quality across groups; most students preferred pre-operational virtual learning.

Conclusions:

• Virtual simulation for root canal filling did not directly improve undergraduate students' filling quality.
• The platform positively influences the transition from theoretical coursework to practical laboratory operations.
• Virtual simulation serves as a valuable supplementary resource for preclinical endodontic education.
