Summary
Using an energized ultrasonic file improved sealer distribution in root canals, filling more accessory canals compared to traditional methods. This study evaluated sealer placement effectiveness in 100 patients.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Effective root canal sealer placement is crucial for endodontic treatment success.
- Accessory canal obturation remains a challenge in preventing persistent infection.
Purpose of the Study:
- To evaluate the effectiveness of an energized ultrasonic file in sealer placement and distribution within the root canal system.
- To compare sealer distribution using an ultrasonic file versus a master gutta-percha cone.
Main Methods:
- In vivo evaluation in 100 patients.
- Sealer placement using either a master gutta-percha cone or an energized ultrasonic file (#20) after irrigation and debridement.
- Canal obturation with gutta-percha via lateral condensation.
- Radiographic assessment of sealer-filled accessory canals.
Main Results:
- A statistically significant difference was observed in the number of radiographically visible accessory canals filled.
- The ultrasonic file method resulted in a higher incidence of filled accessory canals compared to the master cone method.
Conclusions:
- Energized ultrasonic file activation enhances sealer placement and distribution in prepared root canals.
- This technique improves obturation of accessory canals, potentially leading to better endodontic outcomes.
