Successful esthetic dentistry to meet patient satisfaction and produce a progressive impact on someone's personality cannot be succeeded without proper shade selection, both for direct or indirect restoration of dentition. The accurate shade selection is one of the most interesting phases of restoring the natural look of teeth. In clinical practices, dental students should be aware of the various light sources used for shade selection. The purpose of this research is to compare the shade matching ability of clinical and non-clinical students under clinical and correcting light. This comparative cross-sectional study was instigated amongst clinical and non-clinical students of the dental complex of King Faisal University, Kingdom of Saudi Arabia, after obtaining ethical approval from the Research Ethics Committee with reference number (KFU-REC-2022-MAR-EA000518). A total of 102 students assessed the shade under clinical (fluorescent light) and correcting light (handheld Dental Base Light) by using VITA Classical shade guides. Statistical analysis was done using SPSS version 23 (Armonk, NY, USA). The Chi-square test and -test were used to evaluate the association between shade matching scores under correcting and clinical light. Out of 102 students, 41 (40.2%) were non-clinical and 61 (59.8%) were clinical, with a mean age of 21.66 ± 1.397 years. Shade matching scores were found significantly higher ( < 0.001) with the light-correcting device (2.29 ± 1.26) as compared to clinical light (1 ± 1.11) for non-clinical students. Similarly, clinical students also had significantly better ( < 0.001) shade matching with the light-correcting device (4.01 ± 1.34) in comparison to clinical light (2.47 ± 1.25). This study concluded that the shade matching scores under correcting light was significantly better than the results obtained by dental operatory light. Furthermore, it was also evidenced that clinical students' skills in matching shades were significantly improved under a correcting light source as compared to non-clinical students.
成功的美学牙科要满足患者的满意度并对其个性产生积极影响，就离不开对直接或间接修复的牙齿进行适当的比色选择。准确的比色选择是恢复牙齿自然外观最有趣的阶段之一。在临床实践中，牙科学生应该了解用于比色选择的各种光源。本研究的目的是比较临床和非临床学生在临床和矫正光线下的比色匹配能力。这项横断面比较研究是在沙特阿拉伯王国法伊萨尔国王大学牙科综合大楼的临床和非临床学生中进行的，研究获得了研究伦理委员会的伦理批准（KFU-REC-2022-MAR-EA000518）。共有 102 名学生使用 VITA Classical 比色指南在临床（荧光灯）和矫正光（手持牙科基础灯）下评估比色。使用 SPSS 版本 23（Armonk，NY，USA）进行统计分析。卡方检验和 t 检验用于评估矫正光和临床光下比色匹配得分之间的关系。在 102 名学生中，41 名（40.2%）是非临床学生，61 名（59.8%）是临床学生，平均年龄为 21.66 ± 1.397 岁。研究发现，与临床光相比，非临床学生使用矫正光设备（2.29 ± 1.26）的比色匹配得分显著更高（<0.001）。同样，与临床光相比（2.47 ± 1.25），临床学生使用矫正光设备（4.01 ± 1.34）的比色匹配也显著更好（<0.001）。本研究得出结论，与牙科诊室光相比，矫正光下的比色匹配得分明显更好。此外，与非临床学生相比，临床学生在矫正光源下的比色匹配技能也显著提高。
