Summary
This study found that flowable, hybrid, and packable resin composites, along with organically modified ceramics, showed similar effectiveness in preventing microleakage in Class V dental restorations.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
Background:
- Microleakage is a significant concern in Class V restorations, potentially leading to secondary caries and pulp inflammation.
- Evaluating novel restorative materials is crucial for improving clinical outcomes.
Purpose of the Study:
- To compare the microleakage of Class V cavities restored with three resin composites and an organically modified ceramic (ormocer).
Main Methods:
- Class V cavities were prepared with occlusal enamel and gingival dentin margins.
- Teeth were restored with flowable resin composite, hybrid resin composite, packable resin composite, or ormocer.
- Restorations underwent thermocycling and immersion in a dye solution, followed by microleakage assessment.
Main Results:
- No statistically significant differences in microleakage were found between the four restorative material groups.
- This held true for both enamel and dentin margins.
Conclusions:
- All tested restorative materials demonstrated comparable efficacy in minimizing microleakage.
- Clinicians can consider these materials equally effective for Class V restorations regarding marginal seal.
