Hypothesis
There would be no difference in microleakage between tooth and inlays made by direct or indirect technique with and without FRC substructure.
Conclusion
The study suggests that using a fiber reinforced composite substructure in direct inlay fillings does not increase marginal leakage compared to indirect restorations.
Supporting Evidence
- Microleakage in the occlusal area showed significant differences between groups.
- FRC groups had lower microleakage than composite restorations.
- Thickness of cement layer did not show significant difference between groups with indirect technique.
Takeaway
This study looked at how well different types of dental fillings keep out leaks. It found that using a special fiber in the filling doesn't make it leak more than other methods.
Methodology
Forty human premolars were restored using direct and indirect techniques with or without fiber reinforced composite, then tested for microleakage.
Participant Demographics
Forty human premolars free of visible caries.
