Summary
First-year dental students achieved adequate radiant exposure (RE) for light-curing restorations using the Valo Grand Cordless unit. The High Power Plus mode delivered significantly more RE and required less time than Standard mode.
Area of Science:
- Dental Materials Science
- Clinical Dentistry
- Biomedical Engineering
Background:
- Effective light-curing is crucial for dental restoration longevity.
- Assessing student proficiency in light-curing techniques is essential for dental education.
- Standardized methods are needed to evaluate light-curing efficacy.
Purpose of the Study:
- To measure radiant exposure and time for delivering 16 J/cm2 to simulated Class I and Class III restorations.
- To evaluate the performance of first-year dental students using the Valo Grand Cordless light-curing unit.
- To compare the Standard and High Power Plus modes of the light-curing unit.
Main Methods:
- 89 first-year dental students received light-curing lecture and simulation training.
- The Managing Accurate Resin Curing Patient Simulator (MARC-PS) was used for assessment.
- Students performed light-curing twice on Class I and III restorations in Standard and High Power Plus modes.
Main Results:
- 79% of students achieved 16 J/cm2 radiant exposure in both modes on both attempts.
- High Power Plus mode delivered significantly higher radiant exposure.
- High Power Plus mode required less time to achieve 16 J/cm2 radiant exposure.
Conclusions:
- The MARC-PS effectively identifies students needing further instruction in light-curing.
- Utilizing High Power Plus mode or increasing Standard mode time may be necessary for Class I restorations.
- Optimizing light-curing parameters ensures adequate resin polymerization and restoration success.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...
