Enhancing Tooth Reduction Skill in Fixed Prosthodontics Using Case-Based Learning Among Dental Students

Enhancing Tooth Reduction Skill in Fixed Prosthodontics Using Case-Based Learning Among Dental Students: A Quasi-Experimental Study

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

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Conventional teaching group; Participants received conventional teaching methods as part of the standard fixed prosthodontics curriculum.	Behavioral: Conventional Teaching; Traditional lecture-based teaching delivered as part of the standard fixed prosthodontics curriculum.
Experimental: Case-Based Learning (CBL) group; Participants received a case-based learning (CBL) educational intervention in fixed prosthodontics.	Behavioral: Case-Based Learning (CBL); A structured case-based learning approach was used to support active learning, clinical reasoning, and application of theoretical knowledge during fixed prosthodontics teaching sessions.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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)
