1. What is the purpose of the Gutta Percha Injecting Needle?
The Gutta Percha Injecting Needle heats and softens gutta-percha, allowing it to be injected into the prepared root canal during backfill procedures.
2. What temperatures can the Gutta Percha Injecting Needle reach?
The needle operates at adjustable temperatures between 180°C and 230°C, with specific gauge recommendations (e.g., 25G for 180°C–230°C, 23G for 180°C–200°C).
3. How do I install the Gutta Percha Injecting Needle?
After powering off the Fi-G device and letting it cool down for 5 minutes, use the provided wrench to attach the needle by turning it clockwise.
4. Can I bend the Gutta Percha Injecting Needle?
Yes, the needle can be pre-bent to the desired angle using the provided wrench, but the bending angle should not exceed 90°. Avoid bending in transitional areas to prevent breakage.
5. How should I clean the Gutta Percha Injecting Needle?
After each use, clean the needle with pure water (below 45°C), dry with a soft cloth, and store it in a sealed environment to prevent oxidation.
6. Can I reuse the Gutta Percha Injecting Needle?
No, the needle should be discarded after each procedure to ensure patient safety and optimal performance.
7. What should I do if the needle becomes clogged with gutta-percha?
Use the cleaning brush provided with the device to clean out any residual gutta-percha from the needle and heating chamber while the device is still warm.
8. What material is the Gutta Percha Injecting Needle made of?
The Gutta Percha Injecting Needle is made of silver, which provides excellent thermal conductivity for efficiently heating and softening gutta-percha. However, due to its composition, it may discolor when exposed to air, so it is recommended to store unused needles in a sealed environment to prevent oxidation.
