Summary
This study found no significant difference in microleakage for Class 5 resin restorations on various tooth surfaces, regardless of bevelling or groove preparation. Fluoride gel and sealant applications also did not alter these microleakage values.
Area of Science:
- Restorative Dentistry
- Dental Materials Science
Background:
- Microleakage in resin restorations is a persistent clinical challenge.
- Understanding factors influencing marginal integrity is crucial for restoration longevity.
Purpose of the Study:
- To evaluate microleakage in Class 5 resin restorations.
- To assess the impact of cavosurface bevelling and groove preparation on microleakage.
- To investigate the effect of fluoride gel and sealant application on restoration margins.
Main Methods:
- Ninety human teeth underwent Class 5 cavity preparations on buccal, lingual, mesial, and distal surfaces.
- Teeth were assigned to groups for bevelling, groove preparation, or control, with subgroups receiving fluoride gel and/or sealant.
- Restorations were subjected to thermocycling and dye immersion, followed by stereomicroscopic evaluation of microleakage.
Main Results:
- No statistically significant differences in microleakage scores were observed between restorations with or without cavosurface bevelling or groove preparation.
- The application of fluoride gel and/or sealant did not significantly affect the microleakage values across different tooth surfaces.
Conclusions:
- Cavosurface modifications like bevelling or groove preparation do not influence microleakage in Class 5 resin restorations.
- Fluoride gel and sealant applications do not provide additional benefits in reducing microleakage for these types of restorations.
