About this study
Official title: 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
- Conditions
- Medical Education
- Being tested
- Case-Based Learning (CBL), Conventional Teaching
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Case-Based Learning (CBL)Behavioural
A structured case-based learning approach was used to support active learning, clinical reasoning, and application of theoretical knowledge during fixed prosthodontics teaching sessions.
Conventional TeachingBehavioural
Traditional lecture-based teaching delivered as part of the standard fixed prosthodontics curriculum.
| Study group | Role | What they receive |
|---|---|---|
| Conventional teaching group | Active comparator | Participants received conventional teaching methods as part of the standard fixed prosthodontics curriculum. Receives: Behavioral: Conventional Teaching |
| Case-Based Learning (CBL) group | Experimental | Participants received a case-based learning (CBL) educational intervention in fixed prosthodontics. Receives: Behavioral: Case-Based Learning (CBL) |
What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: At the end of the educational intervention (up to 4 weeks)

Primary outcome
Theoretical knowledge examination score
Time frame: At the end of the educational intervention (up to 4 weeks)
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.
Results and safety
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Theoretical knowledge examination score (time frame: At the end of the educational intervention (up to 4 weeks)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2026.
