Use of virtual reality as a learning environment in dentistry

Area of Science:

• Dental Education
• Virtual Learning Environments
• Preclinical Training

Background:

• Traditional preclinical dental education faces limitations in simulating complex clinical situations.
• Virtual worlds offer immersive and interactive learning experiences.
• Second Life (SL) presents a potential platform for supplementary dental education.

Purpose of the Study:

• To compare the effectiveness of 3-dimensional interactive platforms (3DIPs) in Second Life (SL) versus traditional methods for dental education.
• To assess learning gains in understanding concepts, procedural aspects, and spatial interpretation of anatomical structures.
• To evaluate student motivation and engagement with virtual learning tools.

Main Methods:

• A quasi-experimental design with pretest-posttest comparisons was employed.
• Two groups: control (traditional teaching) and experimental (traditional teaching + SL 3DIPs).
• Learning was assessed using a 20-question multiple-choice test; a Student t test analyzed results (α = 0.05).

Main Results:

• The experimental group showed significantly higher posttest scores in understanding concepts and spatial interpretation (P < 0.05).
• No significant difference was found between groups for procedural aspects learning outcomes.
• Students utilizing cooperative methods in SL reported high motivation.

Conclusions:

• Second Life (SL) effectively enhances understanding of complex anatomical interactions difficult to visualize in real-life settings.
• The virtual environment is engaging for students and possesses significant didactic potential for dental education.
• While beneficial for conceptual and spatial learning, SL's impact on procedural skills requires further investigation.
