Summary
Super-EBA, Ketac-fil, and thermoplasticized gutta-percha (TGP) with sealer showed superior sealing ability compared to amalgam-based materials in root-end filling. Super-EBA exhibited the best performance, indicating less microleakage in endodontic procedures.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Effective sealing of root-end cavities is crucial for the success of endodontic surgery.
- Various materials are used for retrofilling, but their sealing capabilities differ.
Purpose of the Study:
- To compare the sealing ability of different retrofilling materials.
- To evaluate microleakage in root-end preparations filled with various materials.
Main Methods:
- 85 single-rooted teeth were obturated with gutta-percha and resected.
- Root-end cavities were prepared and filled with: amalgam/varnish, amalgam/Clearfil Liner Bond II, thermoplasticized gutta-percha (TGP)/sealer, Ketac-fil, or Super-EBA.
- Dye leakage was assessed after India ink immersion and clearing.
Main Results:
- Super-EBA, Ketac-fil, and TGP/sealer showed significantly less leakage than amalgam-based groups (p < 0.05).
- Super-EBA demonstrated significantly less leakage than Ketac-fil and TGP/sealer (p < 0.05).
- No significant difference in leakage was observed between Ketac-fil and TGP/sealer, or between the two amalgam groups.
Conclusions:
- Super-EBA, Ketac-fil, and TGP with sealer are superior retrofilling materials compared to amalgam-based materials.
- Super-EBA provides the best marginal seal among the tested materials.
- Material selection is critical for minimizing microleakage in endodontic surgery.
