Analysis of moral reasoning in dentistry students through case-based learning (CBL).

Purpose: The aim of this study was to develop a tool to analyze the ethical dimensions during dental students' decision making, by using case-based learning (CBL).

Methods: Five clinical scenarios involving ethical aspects addressing different moral dilemmas were selected. The cases were then administered to students during a course on ethics, and the students responded using a narrative technique. To analyze the responses, a criterion inspired by Kohlberg's theory of moral development was used. Subsequently, the data were analyzed statistically, and possible associations between the answers and other variables, such as the student's gender and theoretical knowledge of ethics, were evaluated.

Results: A total of 260 students participated (182 women and 78 men), and 1300 narratives were analyzed. The reliability of the construct, as tested by the Cronbach's alpha and the homogeneity index, was acceptable (0.7). The validity of the construct was also assessed, suggesting a component analysis. The descriptive analysis suggests a certain tendency to solve moral problems by referring to established norms and laws. Furthermore, the correlation anaylysis suggests the interrelation between dimensions linked to patient integrity and respect for the truth, even though this conclusion is not reflected in the component analysis, which only detects a generic component of moral sensitivity. No significant differences by gender were found in the narratives, nor a strong correlation of the responses with theoretical knowledge on ethics.

Conclusion: CBL through the narrative method on ethical dilemmas is an effective tool for assessing dental students' moral competencies and their possible interactions with other variables.
