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.
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.
