Summary
Mineral trioxide aggregate and other advanced materials show minimal microleakage compared to traditional amalgam for root-end fillings. This research aids in selecting superior materials for endodontic procedures.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root-end filling materials are crucial for the success of endodontic surgery.
- Microleakage at the root-end filling interface can lead to treatment failure.
Purpose of the Study:
- To compare the microleakage of various root-end filling materials.
- To evaluate the efficacy of mineral trioxide aggregate, Super-EBA, dentin-bonded resin, Intermediate Restorative Material (IRM), and amalgam.
Main Methods:
- A fluid filtration system was employed to assess microleakage.
- Sixty extracted human single-rooted teeth were prepared and filled.
- Samples were divided into control and experimental groups for material testing.
Main Results:
- Amalgam demonstrated significantly higher microleakage than Super-EBA, dentin-bonded resin, and mineral trioxide aggregate.
- No significant difference in microleakage was found between amalgam and IRM.
- IRM showed no significant difference compared to the other three advanced materials.
Conclusions:
- Mineral trioxide aggregate, Super-EBA, and dentin-bonded resin are superior to amalgam in preventing root-end microleakage.
- IRM performance is comparable to advanced materials, though not statistically superior to amalgam in all comparisons.
