Occasionally an infection can develop or persist after root canal therapy. If this occurs, revision (retreatment) of the root canal may be required. If revision therapy is not successful in eradicating the infection, it may be necessary to surgically remove the infected root tip(s) or apex and the surrounding tissue. This procedure is known as apical micro-surgery or an apicoectomy.
Before the procedure, a thorough examination and diagnosis will be performed. Then the procedure will be explained and a verbal and written consent obtained. On the day of surgery, local anesthetic will be administered and an incision will be made to gain access to the infected area. The entire procedure is done using an ceiling mounted operating microscope with fiber optic lighting. Once the infected area around the apex is cleaned, the tip of your root will be resected and sealed. Then resorbable sutures will be placed and an ice pack applied.
You will be given medication to alleviate discomfort and return home for the rest of the day. Most patients will have minor swelling, occasional bruising and transient numbness. You will be instructed to update your status the day after treatment and will be followed carefully until healing is complete.
