Effectiveness of Using an Instructional Video in Teaching Light-Curing Technique

Area of Science:

• Dental Education
• Restorative Dentistry
• Light-Curing Technology

Background:

• Effective light-curing is crucial for successful dental restorations.
• Dental students require proper training in light-curing techniques to ensure adequate irradiance and radiant exposure.
• Traditional verbal instruction is a common method for teaching this technique.

Purpose of the Study:

• To compare the effectiveness of instructional videos versus verbal instructions in teaching dental students the light-curing technique.
• To assess students' ability to deliver satisfactory irradiance and radiant exposure to simulated cavities using different teaching methods.

Main Methods:

• Sixty dental students were divided into two groups: one received video instruction (V), the other individual verbal instruction (I).
• Students used the Managing Accurate Resin Curing-Patient Simulator (MARC-PS) system to light-cure simulated Class I and III cavities.
• Performance was measured by irradiance and radiant exposure, with comparisons made before and after instruction.

Main Results:

• Both instructional methods led to significant improvements in students' light-curing performance.
• No statistically significant difference was found in mean irradiance or radiant exposure between the video and verbal instruction groups.
• Students found both teaching methods to be effective.

Conclusions:

• Instructional videos are as effective as verbal instructions for teaching the light-curing technique to dental students.
• Video-based instruction is a viable and effective tool for improving students' ability to achieve adequate irradiance and radiant exposure.
• Both methods enable students to deliver sufficient light-curing parameters to simulated cavities.
