Summary
This study compared three root-end filling materials for sealing ability and marginal adaptation. MTA-Angelus showed superior marginal adaptation, while all materials differed significantly in sealing effectiveness.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root-end filling materials are crucial for successful endodontic surgery.
- Evaluating sealing ability and marginal adaptation is essential for material selection.
Purpose of the Study:
- To assess the root-end sealing ability and marginal adaptation of MTA-Angelus, SuperEBA, and Vitremer.
- To compare the performance of these materials using dye leakage and scanning electron microscopy (SEM).
Main Methods:
- Thirty human uniradicular teeth were retrofilled with MTA-Angelus, SuperEBA, or Vitremer.
- Dye leakage evaluation (silver nitrate) assessed sealing ability.
- Scanning electron microscopy (SEM) evaluated marginal adaptation to dentin.
Main Results:
- Significant differences in sealing ability were observed among the three materials (p < 0.05).
- MTA-Angelus demonstrated superior marginal adaptation compared to SuperEBA and Vitremer (p < 0.01).
- No correlation was found between dye leakage and marginal adaptation results.
Conclusions:
- MTA-Angelus exhibits excellent marginal adaptation in root-end fillings.
- Material choice impacts both sealing ability and marginal adaptation in endodontic procedures.
- Different evaluation methods may yield independent results for root-end filling materials.
