Participants were randomly allocated to either a concept map-based instruction group (n = 21) or a conventional lecture-based teaching group (n = 21). Both groups received identical educational content over two instructional sessions delivered by the same instructor. Knowledge was assessed using a validated researcher-developed 12-item multiple-choice examination, and critical-thinking skills were measured using the Persian version of the California Critical Thinking Skills Test before and after the intervention. Between-group and within-group comparisons were performed using independent- and paired-samples t-tests, Randomization description: A total of 42 fifth-semester dental students currently taking the forensic dentistry course were included in the study via a census approach; they were assigned to either a control group or an intervention group. Given the limited number of students, all eligible dental students were recruited using purposive sampling; although random assignment to groups was employed, the study deviated from true randomization and assumed a quasi-experimental design. N/A Forensic Dentistry Education. Intervention 1: Intervention group: Concept map-based instruction in the forensic dentistry course. The course content was reviewed and organized into scenarios, and concept maps were developed following analysis of the content and presented during two instructional sessions. Intervention 2: Control group: Conventional instruction in the forensic dentistry course using lectures and PowerPoint presentations. No - There is not a plan to make this available Justification or reason for not sharing IPD is Due to the need to protect participants’ confidentiality and privacy, and considering the educational nature of the study, there is no plan to make individual participant data (IPD) publicly available.
