The purpose of this study was to survey left-handed (LH) dental students and interns concerning whether they face any problems in their dental education or in their practice of dentistry. The questionnaires were distributed in four dental colleges in different regions in Saudi Arabia. The questionnaire was comprised of sixteen questions to assess the following issues: demographic information, difficulties in dental school or dental practice due to left-handedness, preferred hand in performing different dental procedures, and musculoskeletal complications. The study found that the percentage of LH dental students was around 7 percent (110 out of 1,660). More than half of these participants (n=56) reported that being LH is not a problem in general, while when performing the required dental work, around 51 percent (n=56) agreed to having a problem. The majority (68 percent; n=75) reported that they had a problem with having RH instructors, and 84.5 percent (n=93) responded that their institution is not properly equipped to accommodate LH students. Only 34 percent (n=37) agreed that using facilities of an RH dentist may cause musculoskeletal complications to an LH dentist. The results of this study suggest that dental schools should provide LH students with appropriate equipment and a proper learning environment.
本研究旨在调查左撇子（LH）牙科学生和实习生，了解他们在牙科教育或牙科实践中是否存在任何问题。调查问卷在沙特阿拉伯四个不同地区的四所牙科院校分发。问卷由 16 个问题组成，旨在评估以下问题：人口统计学信息、由于左撇子在牙科学校或牙科实践中遇到的困难、在执行不同牙科程序时更喜欢的手，以及肌肉骨骼并发症。研究发现，LH 牙科学生的比例约为 7%（1660 名学生中有 110 名）。超过一半的参与者（n=56）表示，一般来说，左撇子并不是问题，而在执行所需的牙科工作时，约 51%（n=56）表示存在问题。大多数人（68%；n=75）表示他们与右撇子讲师存在问题，84.5%（n=93）的人表示他们的机构没有配备适当的设备来容纳左撇子学生。只有 34%（n=37）的人同意使用右撇子牙医的设施可能会导致左撇子牙医出现肌肉骨骼并发症。本研究结果表明，牙科学校应为 LH 学生提供适当的设备和适当的学习环境。
