Summary
A new hot obturation technique improved biosealer penetration into dentinal tubules. This method ensures the apical third remains at 37°C, preventing chemical alteration of the biosealer.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root canal anatomy presents challenges for complete filling.
- Single-cone obturation may not ensure comprehensive sealing.
Purpose of the Study:
- Evaluate the temperature of biosealer during a new hot obturation technique.
- Assess biosealer penetration depth into dentinal tubules.
Main Methods:
- Two ex vivo experiments were conducted on mandibular premolars.
- Temperature was measured using K-type thermocouples.
- Biosealer penetration was analyzed using confocal laser scanning microscopy.
Main Results:
- The new hot technique did not deliver heat to the apical third.
- Significantly greater biosealer penetration into dentinal tubules was observed with the new method (Group B) compared to the single-cone technique (Group A).
Conclusions:
- The novel hot modified technique enhances biosealer penetration into dentinal tubules.
- Maintaining the apical 3 mm at 37°C with this technique avoids chemical alteration of the biosealer.
