Abstract

BACKGROUND

This study aimed to assess the performance of preclinical dental male and female students in performing maxillary anterior all-ceramic preparations using a validated analytic rubric system.

METHODS

An analytical rubric for the assessment of maxillary anterior ceramic preparations was used in a preclinical phase study with two evaluators. The grading was based on a 4-point scale for all steps for crown preparation, and the total score was calculated out of 40 points. Differences in rubric parameter scores between male and female students were analyzed via an independent t test. Other tests, such as the kappa test and Pearson's correlation coefficient, were used to measure the associations among grade point average (GPA), evaluators, and gender participants, with p < 0.050 considered a cutoff point for statistical significance.

RESULTS

The study revealed that students of both genders demonstrated high performance, with females scoring a mean of 37.70 ± 1.61 (SD) and males scoring a mean of 36.50 ± 2.36 (SD). A significant difference in the average overall score was recorded by both evaluators (p = 0.034). The highest value was for intact gingival margins and surrounding tissues (3.89 ± 0.31 males, 3.92 ± 0.28 females), and the lowest value was for axial wall reduction (3.50 ± 0.36 males, 3.62 ± 0.42 females). Among the different parameters, only the finish line form parameter was significantly different (p = 0.011), as found by evaluator 1. Inter-rater reliability analysis revealed varying levels of agreement between the evaluators. Strong positive correlations were found between several rubric parameters, but students' GPA had a weak, nonsignificant correlation with their preclinical performance (p = 0.495).

CONCLUSION

The analytic rubric revealed minor gender differences in preclinical performance, with female students performing slightly better. The rubric demonstrated varying inter-rater reliability and positive correlations across parameters. However, GPA showed limited correlation with preclinical performance.

摘要

背景

本研究旨在使用经过验证的分析性评分系统，评估临床前牙科专业男女学生在上颌前牙全瓷修复体预备操作中的表现。

方法

在一项临床前期研究中，两名评估者使用了上颌前牙陶瓷修复体预备的分析性评分标准。牙冠预备所有步骤的评分基于4分制，总分满分为40分。通过独立t检验分析男女学生在评分标准参数得分上的差异。使用其他测试，如kappa检验和皮尔逊相关系数，来衡量平均绩点（GPA）、评估者和性别参与者之间的关联，p < 0.050被视为具有统计学意义的临界值。

结果

研究表明，男女学生均表现出色，女生平均得分为37.70 ± 1.61（标准差），男生平均得分为36.50 ± 2.36（标准差）。两位评估者记录的平均总分均存在显著差异（p = 0.034）。最高值出现在完整的牙龈边缘及周围组织（男生为3.89 ± 0.31，女生为3.92 ± 0.28），最低值出现在轴壁预备（男生为3.50 ± 0.36，女生为3.62 ± 0.42）。在不同参数中，只有评估者1发现精修线形态参数存在显著差异（p = 0.011）。评估者间信度分析显示评估者之间的一致性水平各不相同。在几个评分标准参数之间发现了强正相关，但学生的GPA与他们的临床前表现之间存在弱的、无显著意义的相关性（p = 0.495）。
