Virtual learning objects (VLOs) significantly improved dental students' theoretical knowledge and practical skills in manipulating zinc phosphate cement (ZPC). Students using VLOs demonstrated superior cement handling and knowledge retention compared to traditional methods.
Area of Science:
- Dental Education
- Materials Science in Dentistry
Background:
- Traditional lectures may not fully optimize theoretical knowledge and practical skills for dental materials.
- Virtual Learning Objects (VLOs) offer a potential supplementary tool for enhancing student learning in dentistry.
Purpose of the Study:
- To assess the impact of a Virtual Learning Object (VLO) on undergraduate dental students' theoretical knowledge and practical skills concerning zinc phosphate cement (ZPC).
Main Methods:
- Forty-six dental students were randomized into groups: immediate VLO access, longitudinal VLO access, and two control groups (book/no VLO).
- Participants underwent pre- and posttests for theoretical knowledge and laboratory skill assessments for ZPC manipulation.
- Assessments were conducted by blinded examiners to ensure objectivity.
Main Results:
- Students utilizing the VLO demonstrated superior performance in all theoretical and practical assessments compared to control groups.
- Significant improvements were noted in theoretical posttest scores and reduced film thickness in VLO groups.
- VLO groups exhibited significantly higher setting times, indicating enhanced mechanical properties of the manipulated ZPC.
Conclusions:
- Virtual Learning Objects (VLOs) enhance dental students' understanding and manipulation of zinc phosphate cement.
- VLO integration leads to superior clinical handling skills and improved long-term knowledge retention.
- VLOs represent an effective educational tool for improving dental material proficiency.
