A pilot study on the application of a digital dental teaching evaluation system in Class II cavity preparation teaching.

Abstract

Objective: To explore the feasibility of applying the digital evaluation system in the homogeneous training and qualification evaluation of teaching faculty in the preclinical simulation teaching of G.V. Black Class II cavity tooth preparation in operative dentistry.

Methods: Eighteen clinicians who graduated with Ph.D. and were about to participate in the operative dentistry preclinical teaching at the Hospital of Stomatology, Sun Yat-sen University, were selected to practice the G.V. Black Class II cavity tooth preparation of the left mandibular first molar by using the Aizhixing Digital Dental Virtual Teaching Evaluation System DHC210. Through continuous practice and assessment, we evaluated whether there were changes in their examination scores and operation time after practicing with multiple teeth. Meanwhile, we evaluated the condition of Class II cavity tooth preparation before and after practices using Fair Grader 2000, a Dental Digital Teaching Practice Evaluation System, and combined it with questionnaires to examine the teaching effectiveness of this training.

Results: As the number of exercises increased, there was a tendency for the result scores of the four tests of Aizhixing to increase (P > 0.05), and the operating time was progressively less (P < 0.05). The results of Fair Grader 2000 showed that dental clinicians who had completed their standardized residency training had higher and more stable scores than those who were ongoing (P < 0.05). The questionnaire survey results showed that it was necessary to apply Aizhixing to Class II cavity tooth preparation teaching activities, which can effectively improve students' theoretical knowledge and the level of cavity preparation skills.

Conclusion: The application of the digital real-time evaluation system of Aizhixing and the digital evaluation system help to improve the efficiency and objective assessment of Class II cavity tooth preparation, which provides a certain reference basis for achieving high-quality and homogeneous teaching and reform of oral endodontics.
