Abstract

Objectives: This study investigated the effect of different magnification levels of the Galilean system loupes on dental students' working posture and the quality of cavity preparations.

Materials and methods: An experimental study was conducted, with the response variables being compliance with ergonomic posture requirements (measured using the Compliance Assessment of Dental Ergonomic Posture-CADEP) and quality of cavity preparation (assessed using the Class One Cavity Preparation Assessment-COCA). The independent variable was the magnification level of the Galilean system loupe, tested at four levels: naked eyes, 2.5×, 3.0×, and 3.5×. Second-year undergraduate dental students (N = 40) participated and were divided into Groups I and II. Each student performed cavity preparation at each magnification level, resulting in four preparations per student. Group I started with the naked eye, whereas Group II began with loupes at different magnifications. After 1 week, the conditions were reversed. Working postures were captured in photographs and analysed using CADEP, whereas the quality of the cavity preparations was assessed using COCA. After verifying normality and sphericity, a one-way repeated measures ANOVA with Bonferroni post hoc test (α = 5%) was conducted.

Results: The second results showed that at 3.0× magnification, both compliance with ergonomic posture and the quality of class I cavity preparations were significantly superior compared to the naked eye (p < 0.001).

Conclusions: Galilean loupes of 3.0× provided the best balance, improved working posture, and enhanced procedural quality.

伽利略镜对牙科学生体位及造牙质量的影响。
目的:研究不同倍率的伽利略系统放大镜对牙科学生工作姿势和口腔准备质量的影响。材料和方法:实验研究,响应变量为符合人体工学姿势要求(使用牙科人体工学姿势依从性评估- cadep测量)和腔体制备质量(使用一类腔体制备评估- coca评估)。自变量为伽利略系统放大镜的放大倍数,分为裸眼、2.5倍、3.0倍、3.5倍四个水平。参加本研究的牙科本科二年级学生40名,分为第一组和第二组。每个学生在每个放大倍率下进行空腔准备,每个学生四次准备。第一组从肉眼开始,而第二组从不同倍率的放大镜开始。1周后,情况逆转。用照片捕捉工作姿势并使用CADEP进行分析,而使用COCA评估腔制剂的质量。在验证正态性和球形性后,采用Bonferroni事后检验(α = 5%)进行单向重复测量方差分析。结果:第二项结果显示,在3.0倍放大镜下,与裸眼相比,符合人体工程学姿势的依从性和I类腔体制备的质量均显著优于裸眼(p)。结论:3.0倍的伽利略镜提供了最佳的平衡,改善了工作姿势,提高了手术质量。

期刊介绍: The aim of the European Journal of Dental Education is to publish original topical and review articles of the highest quality in the field of Dental Education. The Journal seeks to disseminate widely the latest information on curriculum development teaching methodologies assessment techniques and quality assurance in the fields of dental undergraduate and postgraduate education and dental auxiliary personnel training. The scope includes the dental educational aspects of the basic medical sciences the behavioural sciences the interface with medical education information technology and distance learning and educational audit. Papers embodying the results of high-quality educational research of relevance to dentistry are particularly encouraged as are evidence-based reports of novel and established educational programmes and their outcomes.
