In addition, this type of procedure is commonly used when an endodontic retreatment is not recommended. While an endodontic retreatment can correct a number of problems associated with a previous root canal procedure, apicoectomy is more suitable for advanced root canal complications. In some instances, a retreatment can be attempted first followed by a surgery, if the retreatment is not successful. Persistent infections and inflammation associated with a root canal treatment require some type of attention whether it is retreatment or an apicoectomy.
That said, there are some clear symptoms or conditions that could indicate an apicoectomy may be appropriate for a particular patient. For example, any condition or situation that interferes with normal healing after a standard root canal may require apicoectomy. Also when several tiny branches located along the side of the main root canal cannot effectively be cleaned and properly sealed, this type of procedure is warranted. Another case where surgery would be appropriate is when a root canal has a pronounced curve making it difficult or impossible for endodontic tools to reach the root tip. When this happens, apicoectomy is typically the best solution.
