Brief Summary

This study aimed to evaluate the effectiveness of CBL compared to traditional lecture-demonstration methods in enhancing the foundational knowledge and practical tooth reduction skills of dental students in fixed prosthodontics. Participants were assigned to an experimental group (n=30) receiving four weekly 90-minute CBL sessions and a control group (n=30) receiving traditional lectures and clinical demonstrations

Conditions

Medical Education

Outcome Measures

Primary Outcomes (1)

• Theoretical knowledge examination score

  Students' theoretical knowledge in teeth preparation in fixed prsothdontics was assessed using scores obtained from a structured written theoretical examination (score range: 0-10), where higher scores indicate better theoretical knowledge. The examination was conducted as part of the course assessment.

  At the end of the educational intervention (up to 4 weeks)

Study Arms (2)

Conventional teaching group

ACTIVE COMPARATOR

Participants received conventional teaching methods as part of the standard fixed prosthodontics curriculum.

Behavioral: Conventional Teaching

Case-Based Learning (CBL) group

EXPERIMENTAL

Participants received a case-based learning (CBL) educational intervention in fixed prosthodontics.

Behavioral: Case-Based Learning (CBL)

Interventions

Case-Based Learning (CBL) BEHAVIORAL

A structured case-based learning approach was used to support active learning, clinical reasoning, and application of theoretical knowledge during fixed prosthodontics teaching sessions.

Case-Based Learning (CBL) group

Conventional Teaching BEHAVIORAL

Traditional lecture-based teaching delivered as part of the standard fixed prosthodontics curriculum.

Conventional teaching group
