Endodontic Microsurgery
What Is Endodontic Microsurgery?
Endodontic microsurgery, also known as a root-end resection or apicoectomy, is a surgical procedure that may be recommended when a persistent infection remains after conventional root canal treatment or retreatment.
When Is Microsurgery Indicated?
Microsurgery may be necessary when:
- Infection persists at the tip of the root after root canal treatment
- A biopsy of the surrounding tissue is needed
- The root tip has a fracture or other defect
- Conventional retreatment is not possible or not advisable
The Microsurgery Procedure
-
Incision and Visualization
The endodontist makes a small incision in the gum tissue to expose the underlying bone and the tip of the root. Using a dental operating microscope, the area is carefully visualized to identify the source of the problem.
-
Root-End Resection and Seal
The very tip of the root is removed (resected), along with any infected tissue. A small biocompatible filling material is placed to seal the end of the root canal and prevent further infection.
-
Sutures and Healing
The gum tissue is repositioned and sutured closed. Over time, the bone heals around the root tip. Sutures are typically removed within a few days.
Other Surgical Procedures
In addition to apicoectomy, endodontic microsurgery may include:
- Root Repair — Repairing damaged or perforated roots
- Root Amputation — Removing one root of a multi-rooted tooth
- Resorptive Defect Treatment — Addressing areas where the tooth structure is being reabsorbed
