The digital training system with OPRS and RDTES might be a good alternative to the traditional training method in the preclinical course of dental practice.
Objectives The aim was to evaluate the effectiveness of a pre‐clinical training of ceramic crown preparation using the Virtual Educational System for Dentistry. Material and Methods Fifty‐seven dental students were recruited to prepare a ceramic crown under the guidance of the Real‐time Dental Training and Evaluation System (RDTES) in order to collect pre‐learning data. They participated in the online virtual learning course independently on the Virtual Learning Network Platform (VLNP). One week later, the students were invited to complete their post‐learning crown preparation with the RDTES. A questionnaire survey explored students' perceived benefits or drawbacks of the virtual educational system. Students were allocated into Group A (n = 15), B (n = 24) and C (n = 18) based on their pre‐learning performance. Differences of assessment results amongst different groups were evaluated by ANOVA and Kruskal‐Wallis tests. The pre‐ and post‐learning assessment results in all groups were compared using paired t tests or Wilcoxon signed rank tests. Results The error scores for four assessment items (instrument selection, preparation section, preparation reduction, preparation surface and profile) and total score of outcome assessment after the virtual learning were significantly different with those before the virtual learning (P < 0.05). There were significant interactions between time and student group in the mean scores of process and outcome assessments (P < 0.001), except for the assessment item “damage of adjacent teeth.” Conclusion The application of a Virtual Educational System for Dentistry with the VLNP and RDTES in pre‐clinical operative training helps students improve their clinical skills.
Dental anatomy is an integrated, core fundamental dental course, which prepares students for all future clinical dental courses. This study aimed to build up an online dental learning platform of micro‐computed tomography‐based three‐dimensional (3D) tooth models with pulp cavity, and to further evaluate its effectiveness for dental anatomy education using a cohort study. First, ninety‐six extracted permanent teeth were scanned by micro‐computed tomography and the enamel, dentine, and pulp cavity of each was distinguished by different grey‐scale intensities using Mimics software. Three‐dimensional images allowed further discrimination and insights into permanent three‐rooted premolars, central tip, and dental diseases including deep caries and wedge‐shaped defects. Furthermore, a second mesiobuccal canal (MB2) in maxillary permanent molar teeth and Vertucci type III root canal configuration in mandibular anterior teeth could be detected using the 3D analytical tool. A digitized 3D tooth model learning platform was implemented. Last, two groups of dental students were assessed to evaluate the effect of 3D models on dental anatomy education. Participants in the Digital group were allowed to use the online dental learning platform freely after class, while the participants in the Traditional group were not. Assessment quizzes showed that participants' scores improved in the Digital group with the use of the learning platform compared with scores in the Traditional group. A questionnaire survey indicated that the participants had a positive attitude toward the 3D models. Thus, adding digital 3D resources to a traditional curriculum may have a positive effect on academic achievements.
Introduction Clinical practice of dentistry entails the use of indirect vision using a dental mirror. The Mirrosistant is a device that helps dental students become proficient with use of indirect vision mirror operation. This study aimed to explore the role of the Mirrosistant on students’ performance with the virtual simulation dental training system. Materials and methods A total of 72 dental students were equally assigned to the Control group and the Experimental group. Subsequently, Mirrosistant was used to conduct a series of mirror training exercises in the Experimental group. The training consisted of tracing the edge and filling in the blank of the prescribed shape, as well as preparing the specified figure on raw eggs using indirect vision via Mirrosistant. Next, both groups were examined using the SIMODONT system, a virtual reality dental trainer, for mirror operation. In addition, a five-point Likert scale questionnaire was used to assess student feedback by using Mirrosistant. Results The mirror operation examination conducted by the SIMODONT system revealed that mirror training using Mirrosistant had statistically improved students’ performances (score: 80.42 ± 6.43 vs. 69.89 ± 15.98, P = 0.0005) and shorten their performance time of mirror operation (time of seconds: 243.28 ± 132.83 vs. 328.53 ± 111.89, P = 0.0013). Furthermore, the questionnaire survey indicated that the participants had positive attitudes toward the mirror training using Mirrosistant. Most students believed that the mirror training device could improve their perceptions of direction and distance, as well as their sensations of dental operation and dental fulcrum. Conclusion Mirror training using Mirrosistant can enhance dental students’ mirror perceptual and operational skills on virtual simulation dental training system.
