Enhancement of students' knowledge is essential in improving their clinical skills and performance. Thus, the curriculum should be prepared to achieve a better outcome. The current study aimed to determine the dental students' and interns' basic knowledge towards dental luting cements and their application in dental practice to improve the theoretical and clinical training sections.
A cross-sectional study was conducted among dental students and interns at three Colleges of Dentistry in the Kingdom of Saudi Arabia between September 2019-June 2020. An online questionnaire was used which included demographic data, questions about luting cement usage, cementation techniques, and commonly used cements in dental clinics. Descriptive analysis and chi-square test were used to show the association between level of dental education and the use of dental cements using SPSS software. The significance level was set at 5%.
The total respondents were 626 dental students/interns of whom 78.8% were undergraduate dental students. Participants who reported undergraduate studies as the source of information were 79.7%. The type of restoration was the main factor in luting cement selection (62.6%). Concerning the isolation technique in cementing laminate veneers, 49.7% used dri-angles, cotton rolls and saliva ejectors. Dual-cure resin cement was the most common cement used in all the mentioned restorations except in pressed porcelain laminate veneers and cement-retained implant-supported restorations.
Students' knowledge and practice in managing dental implants and porcelain laminate veneers need to be improved. The selection of a luting agent for a given restoration by students and interns was based on the basic knowledge, available cement, and the type of restoration. Awareness towards the management of short prepared teeth and custom-made cast posts and cores is also limited.
增强学生的知识对于提高他们的临床技能和表现至关重要。因此，课程应该精心设计，以取得更好的效果。本研究旨在确定沙特阿拉伯三个牙科学院的牙科学生和实习生对牙科水门汀的基础知识及其在牙科实践中的应用，以改进理论和临床培训部分。
本研究采用横断面研究，于 2019 年 9 月至 2020 年 6 月在沙特阿拉伯的三个牙科学院对牙科学生和实习生进行调查。使用在线问卷，内容包括人口统计学数据、水门汀使用、粘结技术以及牙科诊所中常用水门汀的问题。使用 SPSS 软件进行描述性分析和卡方检验，以显示牙科教育水平与牙科水门汀使用之间的关系。显著性水平设定为 5%。
共有 626 名牙科学生/实习生参与了研究，其中 78.8%为本科牙科学生。报告本科学习是信息来源的参与者占 79.7%。修复类型是选择水门汀的主要因素（62.6%）。在粘结层压贴面时，49.7%的人使用 dri-angles、棉卷和唾液抽吸器进行隔离技术。除了在压瓷层压贴面和粘结固位种植体支持修复体中，双固化树脂水门汀是所有提到的修复体中最常用的水门汀。
学生在管理牙科植入物和瓷层压贴面方面的知识和实践需要提高。学生和实习生对特定修复体选择水门汀的依据是基础知识、可用的水门汀以及修复体的类型。对短牙预备和定制铸造桩核的管理意识也有限。
