摘要

目的

评价虚拟评估系统用于口腔医学生后牙金属冠牙体制备结果评分的可行性。

方法

共50名大学四年级的学生参加了后牙金属冠牙体制备实验教学课程，采用虚拟评估系统对学生进行指导，并抽取38名学生分别由虚拟评估系统和教师对牙体制备结果进行评分，并对二者的评分结果进行相关性分析。采用SPSS 22.0进行相关性分析和差异性检验。

结果

虚拟评估系统评分与教师评分结果相关性一般（皮尔森相关系数为0.267）。虚拟评估系统评分（60.87±8.73）显著低于教师的评分（74.71±6.56），差异有统计学意义（

0.001），二者评分结果之间的区别主要体现在邻牙损伤评分和不及格分数的评分。

结论

虚拟评估系统可以辅助教师发现并总结学生在后牙金属冠牙体制备中的易错点，提高学生牙备练习的效率和效果，可作为后牙金属冠牙体制备评分工具。

Abstract

Objective

To evaluate the feasibility of a virtual evaluation system for scoring posterior metal crown tooth preparation by dental students.

Methods

A total of 50 fourth-year undergraduate students participated in the experimental course on posterior metal crown tooth preparation. A virtual evaluation system was used to guide the students. Tooth preparation of 38 students was scored by both the virtual evaluation system and teachers. A correlation analysis was performed for the two sets of scores. SPSS 22.0 was used for correlation analysis and significance test.

Results

The scores from the virtual evaluation system and teachers showed moderate correlation and a Pearson correlation coefficient of 0.267. The score from the virtual evaluation system (60.87±8.73) was significantly lower than the score given by the teachers (74.71±6.56) (

0.001). The main differences between the two scoring methods were observed in the assessment of adjacent tooth damage and the proportion of failing scores.

Conclusions

The virtual evaluation system can assist teachers to identify and summarize the error-prone points in the preparation of posterior metal crown tooth

and help students improve the efficiency and effectiveness of tooth preparation practice. The virtual evaluation system can be used as a tool for scoring posterior metal crown tooth preparation.
