Preparation and Safety:
Ensure you have the necessary personal protective equipment (PPE), including gloves, mask, and eyewear.
Prepare the patient and isolate the tooth using a rubber dam for infection control.
Access Opening:
Create an access opening in the tooth to gain access to the root canals, typically using a high-speed handpiece and appropriate burs.
Initial Exploration and Working Length Determination:
Use smaller-sized files or explorers to locate and explore the root canals.
Determine the working length by taking X-rays and measuring. The working length is the point at which the file should reach within the canal.
Irrigation and Lubrication:
Use an irrigating solution (e.g., sodium hypochlorite) to disinfect and lubricate the canals. This helps in the removal of debris and facilitates file movement.
Mani Flexile Files Selection:
Select the appropriate Mani Flexile File (25mm) based on the size and curvature of the root canal. Ensure it’s properly sterilized.
Instrumentation:
Gently insert the Flexile File into the canal and advance it slowly toward the working length.
Use a “watch-winding” or “quarter-turn” motion while applying gentle apical pressure.
Avoid using excessive force, as this can lead to file separation or canal transportation.
Use the file sequentially, moving from smaller to larger sizes as needed to clean and shape the canal.
Irrigate and Recapitulate:
Periodically remove the file from the canal.
Irrigate the canal to remove debris and disinfect it.
Recapitulate by reinserting the file gently to the working length.
Cleaning and Shaping:
Gradually progress to larger Flexile Files to clean and shape the canal.
Continue irrigating as needed to keep the canal clear of debris.
Final Cleaning:
Use final irrigation with an EDTA solution to remove the smear layer and any remaining debris.
Obturation:
Once the canal is cleaned and shaped, it can be obturated with suitable filling material, such as gutta-percha, using the chosen obturation technique.
