背景：在牙科实践中，左右混淆可能导致医源性事故，因此可以严重关注患者护理。因此，本研究的目的是评估牙科学生的左右分辨能力。本研究旨在确定影响学生辨别能力的各种因素之间的关系。材料和方法：所有一年级到四年级的牙科学生都被问及他们的性别、课程年份和惯用手。他们还被要求用李克特五分制来记录他们感知到的歧视能力，并提到使用任何方法来帮助进行左右歧视。修正卑尔根测试用于确定参与者区分左右的能力。这个测试有三个部分——所有的人物都是从正面看的，从背面看的，以及从前后交替看的。对所得值进行统计学分析。结果：男性（43.25±4.52）与女性（42.12±4.53）的RLD能力差异无统计学意义。即使是辨别能力也与学生的临床暴露无显著相关。使用学习过的辨证技巧的学生得分（41.95±4.58）明显低于未使用辨证技巧的学生得分（43.40±4.30）。结论：齿科学生的左右辨别能力与临床暴露无显著相关。没有使用任何技术来帮助他们区分左右的学生比使用一些技术的学生表现得更好。左右混淆更多发生在需要心理旋转的情况下。
Background: Right-left confusion in dental practice may lead to iatrogenic mishaps and thus can be of serious concern with respect to the patient care. Hence, the purpose of this study was to assess the right-left discrimination (RLD) ability among dental students. The study aims to determine the relation of various factors that can affect the students' discriminating ability. Materials and Methods: All consented dental students from first year to fourth year were asked to mention their gender, course year, and handedness. They were also asked to record their perceived discriminatory ability on a five-point Likert scale and to mention the use of any method to aid in right-left discrimination. Modified Bergen test was used to determine the ability of the participants to differentiate right from left. The test had three subsections - all figures viewed from front, from back, and alternating views from back and front. The values obtained were statistically analysed. Results: There was no significant difference in the RLD ability between males (43.25 ± 4.52) and females (42.12 ± 4.53). Even the discriminatory ability had no significant association with students' clinical exposure. Students who used learnt technique for differentiation had significantly lower scores (41.95 ± 4.58) than those without any technique (43.40 ± 4.30). Conclusion: There was no significant association between gender and clinical exposure in the right-left discrimination ability among the dental students. Students who did not use any technique to aid them in differentiating right and left performed better than those who used some technique. Right-left confusion was more in situations where mental rotation was required.
