Name of the Procedure:

Common Name: Retreatment of Root Canal Therapy Medical Term: Endodontic Retreatment of a Molar

Summary

Retreatment of previous root canal therapy involves cleaning, disinfecting, and resealing a previously treated molar that has not healed correctly or has developed new issues.

Purpose

This procedure addresses infections or persistent inflammation in a previously treated molar. The goal is to eliminate the infection, alleviate pain, and preserve the natural tooth.

Indications

• Persistent or recurring tooth pain
• New infection or abscess formation post-initial root canal
• Failure of previous root canal therapy to heal properly
• New decay or damage compromising the original root canal

Preparation

• Pre-procedure consultation with an endodontist
• Diagnostic X-rays to assess the condition
• Follow standard oral hygiene routines
• Discuss any medications or health conditions with the healthcare provider

Procedure Description

1. Anesthesia: Local anesthesia is applied to numb the tooth and surrounding area.
2. Access: The endodontist reopens the tooth to access the root canal filling materials.
3. Cleaning: Old filling materials and any residual infection are removed using specialized files.
4. Disinfection: The canal is disinfected to remove any remaining bacteria.
5. Shaping: The canal is reshaped as needed.
6. Filling: The cleaned and disinfected canal is refilled with new sealing materials.
7. Seal and Protect: The tooth is resealed, and a temporary or permanent filling/crown is placed.

Tools and Equipment:

• Endodontic files
• Irrigating solutions for disinfection
