The current study aims to investigate the utilization of an analytic rubric system to assess the performance of preclinical dental students in executing root canal treatment for a single canal maxillary anterior tooth. An analytic rubric comprising three parameters was developed for the preparation of root canal treatment of single canal maxillary anterior tooth by 34 fourth-year dental students (17 males and 17 females) in a preclinical endodontic course. Three examiners independently assessed the students' performance on access cavities, cleaning and shaping, and obturation using a 5-point scale. The total scores were calculated out of 15 points. The reliability of the rubric was confirmed using the ICC (intraclass correlation coefficient). Pearson correlation analysis was employed to measure the association between grade point average (GPA) and gender with the outcome of single canal root canal treatment and overall rubric scores from different examiners. All the students received an excellent (4/5) rating on all parameters, with no significant differences in overall rubric grading between genders (p-value 0.797). The interexaminer reliability assessed using the Kappa test revealed good to high reliability for access cavity and obturation but low reliability for cleaning and shaping. Meanwhile, the intraexaminer reliability evaluated using ICC was excellent, with values of over 0.60 for all the measured parameters. A significant correlation was observed between the GPA and the overall rubric scores from two examiners. This study found no significant gender differences in performance for root canal treatment of a single canal tooth during the preclinical endodontic phase, with an excellent rating achieved for all the parameters.
本研究旨在探讨使用一种分析性评分系统来评估牙科临床前学生对上颌单根管前牙进行根管治疗的操作表现。为34名牙科四年级学生（17名男性和17名女性）在临床前牙髓病课程中进行上颌单根管前牙根管治疗的操作制定了一个包含三个参数的分析性评分标准。三名考官使用5分制独立评估学生在开髓、清理成形和充填方面的表现。总分满分为15分。使用组内相关系数（ICC）来确定评分标准的可靠性。采用Pearson相关分析来衡量平均绩点（GPA）和性别与单根管根管治疗结果以及不同考官的总体评分之间的关联。所有学生在所有参数上都获得了优秀（4/5）的评分，性别之间在总体评分上没有显著差异（p值为0.797）。使用Kappa检验评估的考官间信度显示，开髓和充填的信度良好至高，而清理成形的信度较低。同时，使用ICC评估的考官内信度非常好，所有测量参数的值均超过0.60。观察到GPA与两名考官的总体评分之间存在显著相关性。本研究发现，在临床前牙髓病阶段，单根管牙齿根管治疗的操作表现不存在显著的性别差异，所有参数均获得优秀评分。
