The Impact of Education on the Ability to Determine Composite Color in Dental Students: A Semi-Experimental Study

Abstract

Introduction: Matching tooth color with restoration is a crucial task in restorative dentistry. Aesthetic dental education plays a significant role in training individuals on color matching. Therefore, this study aims to investigate the impact of education on the ability to determine composite color in dental students.

Methods: In this semi-experimental study, 40 clinical dental students were randomly assigned to control and experimental groups. Initially, both groups were evaluated for their color assessment abilities. The experimental group then received one-hour training from a specialist in restorative and aesthetic dentistry on proper color determination, while the control group received no intervention. To assess their ability to determine tooth color, students were asked to match six composite samples with a color selection set made from the same composites. Statistical analysis of the data was performed using SPSS software and the Chi-square statistical test.

Results: The ability to determine composite color in all samples (except sample 1) significantly improved after training compared to before training (P<0.05). There were no significant statistical differences in the ability to determine composite color based on gender (except in sample 2). However, individuals without a history of wearing glasses performed significantly better than those with such a history in samples 2 and 6 (P<0.05). Additionally, ninth-semester students showed a significantly better ability to determine composite color compared to tenth and eleventh-semester students in samples 1, 2, 4, and 6 (P<0.05).

Conclusion: Education greatly influences the ability of dental students to determine composite color accurately. This study highlights the importance of proper training in color matching for dental students, particularly in restorative dentistry.
