Summary
The Trifecta system showed better root canal sealability but poorer radiographic quality compared to lateral condensation. Lateral condensation offered superior radiographic outcomes in this study.
Area of Science:
- Endodontics
- Dental Materials Science
- Restorative Dentistry
Background:
- Root canal obturation is crucial for endodontic treatment success.
- Gutta-percha is a common root canal filling material.
- Evaluating new obturation systems is essential for improving clinical outcomes.
Purpose of the Study:
- To compare the radiographic quality and sealability of root fillings.
- To evaluate lateral condensation versus the Trifecta obturating system.
- To assess the impact of canal shape on obturation techniques.
Main Methods:
- Extracted human teeth were prepared with parallel or flared canal shapes.
- Root canals were obturated using lateral condensation or the Trifecta system.
- Sealability was assessed via dye penetration; radiographic quality was rated on a 4-point scale.
Main Results:
- Trifecta system showed significantly less apical dye penetration (better sealability) than lateral condensation (P < 0.001).
- Lateral condensation achieved significantly better radiographic quality scores than Trifecta (P < 0.001).
- Trifecta technique resulted in significantly more apical sealer extrusion (P < 0.001).
Conclusions:
- The Trifecta system offers superior sealability but poorer radiographic quality compared to lateral condensation.
- Clinical choices between systems depend on prioritizing sealability versus radiographic visualization.
- Further research may explore modifications to improve Trifecta's radiographic visibility.
