Clinical instructional strategies and the climate in which teaching and learning take place have a significant impact on the quality of dental education. Therefore, this study aimed to evaluate the impact of early microsurgery training on the skills of dental intern students who are planning to join an oral and maxillofacial surgical field (DIS) as compared with junior residents within an oral and maxillofacial surgery department who had no microsurgery experience (JR).
A total of 100 trainees, 70 were DIS, while the other 30 were JR. The average age was 23.87 ± 2.05 years for DIS group and 31.05 ± 3.06 for JR group. All trainees attended a microsurgical course (theoretical and practical parts) for seven days within a Microvascular Laboratory for Research and Education of a university-affiliated tertiary hospital. Two blinded examiners had assessed the performance of trainees independently using a specific scoring system. The independent sample t-test was used to compare the effect of microsurgery training between DIS and JR groups. The significance level was set at 0.05.
The DIS group had showed higher attendance rate than JR group (p < 0.01), with a lower absence score in DIS than JR groups (0.33 ± 0.58 vs. 2.47 ± 1.36). The total score of the theoretical test was significantly different between both groups (p < 0.01). In this context, the DIS group had revealed higher total score than JR group (15.06 ± 1.92 vs. 12.73 ± 2.49). In term of tissue preservation, there was a significant difference between both groups, with the DIS had better performance score than JR (1.49 ± 0.51 vs. 0.93 ± 0.59). Further, the practical exam score was significantly higher in DIS group than JR group (p < 0.01).
Overall, the performance of dental intern students was favourably compared with junior residents in most aspects. Therefore, it is promising and essential for dental colleges to add a microsurgery course to the curriculum of dental intern students who plan to specialize in oral and maxillofacial surgery.
临床教学策略和教学环境对口腔医学教育质量有重大影响。因此，本研究旨在评估早期显微外科培训对计划从事口腔颌面外科领域的口腔实习学生（DIS）技能的影响，并与口腔颌面外科部门无显微外科经验的初级住院医师（JR）进行比较。
共有 100 名实习生参加，70 名为 DIS，30 名为 JR。DIS 组平均年龄为 23.87±2.05 岁，JR 组为 31.05±3.06 岁。所有实习生均在大学附属医院的微血管实验室接受为期 7 天的显微外科课程（理论和实践部分）。两位盲评者使用特定的评分系统独立评估实习生的表现。采用独立样本 t 检验比较 DIS 和 JR 组之间的显微外科培训效果。显著性水平设为 0.05。
DIS 组的出勤率高于 JR 组（p<0.01），缺勤评分低于 JR 组（0.33±0.58 比 2.47±1.36）。两组理论考试总分差异有统计学意义（p<0.01）。在此背景下，DIS 组的总分高于 JR 组（15.06±1.92 比 12.73±2.49）。在组织保存方面，两组差异有统计学意义，DIS 组的表现评分优于 JR 组（1.49±0.51 比 0.93±0.59）。此外，DIS 组的实际考试得分明显高于 JR 组（p<0.01）。
总体而言，口腔实习学生的表现与大多数方面的初级住院医师相比更为出色。因此，对于口腔医学院来说，在口腔颌面外科领域有计划的口腔实习学生课程中增加显微外科课程是有希望且必要的。
