Summary
Lateral condensation demonstrated superior sealing ability in root canal filling, showing less leakage compared to other techniques. Ultrasonic activation and lateral condensation also offered better control over filling length.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root canal filling is crucial for endodontic treatment success.
- Effective obturation prevents coronal microleakage and bacterial invasion.
- Various techniques exist, each with potential advantages and disadvantages.
Purpose of the Study:
- To quantitatively and qualitatively compare four root canal filling techniques.
- To assess material adaptation to the canal wall and leakage.
- To evaluate radiographic adaptation and control of filling length.
Main Methods:
- Four techniques were tested: lateral condensation, McSpadden compaction, ultrasonic activation (Enac), and thermoplastic injection (Ultrafil).
- Electrochemical and linear dye penetration methods were used for quantitative leakage assessment.
- Radiographic evaluation assessed adaptation and filling length control.
Main Results:
- Electrochemical analysis showed minimal differences in adaptation among techniques.
- Lateral condensation exhibited a higher proportion of teeth with no leakage.
- Radiographic evaluation indicated similar apical adaptation for all techniques.
- Lateral condensation and ultrasonic activation provided superior control of filling length.
Conclusions:
- Lateral condensation appears to offer better marginal adaptation and reduced leakage.
- Ultrasonic activation and lateral condensation provide enhanced control over root canal filling length.
- Technique selection may influence the success of endodontic obturation.
