Illustration of self-perceived knowledge, skills, and interests in undergraduate dental students using a visual metaphor- results of a monocentric cross-sectional study.

Background: Self-assessment and self-reflection of competencies are crucial skills for undergraduate students. This monocentric cross-sectional study aims to assess the self-perceived knowledge, skills and interests in conservative dentistry and periodontology of third-, fourth-, and fifth-year dental students by the Pictorial Representation of Illness and Self-measure (PRISM).
Methods: Seventy-five undergraduate dental students (n = 25 of each year) who studied between 2021 and 2022 at the Department of Cariology, Endodontology and Periodontology at the University of Leipzig, Germany, were included. All of them underwent a PRISM-based interview regarding their perceived knowledge, practical skills, and interests in conservative dentistry as well as its sub-disciplines. The distances in the PRISM task (in millimeters) were measured and compared between the groups. Spearman's Rho was used to reveal correlations between knowledge, skills, and interests in the cohort.
Results: Perceived theoretical knowledge and practical skills differed significantly between groups for the sub-disciplines periodontology, cariology, restorative dentistry and preventive dentistry (p < 0.05). However, students' interests did not significantly vary between groups (p > 0.05). In the field of conservative dentistry and its sub-disciplines, significant moderate to high positive correlations were found between knowledge and skills (p < 0.01), and weak to moderate positive correlations were found between interests and knowledge (p < 0.05). Regarding the relationship between perceived interests and skills, only restorative dentistry, endodontology and periodontology were significant and only moderate to weak correlations were found (p < 0.05).
Conclusion: PRISM revealed differences in perceived knowledge and skills between third-, fourth-, and fifth-year dental students. Correlations were found between perceived knowledge and skills, as well as between interests and knowledge. PRISM may be a promising tool to support students and teachers in dental education.
