The teeth are held in place by roots which go into the jawbone. Nerves and blood vessels enter the tooth through the end of the root (called the apex) and then pass through a canal inside the root to the pulp chamber. The pulp chamber is present inside the crown--the part of the tooth that is seen in the mouth. In root canal treatment, the canals are cleaned and the inflamed or infected tissue is removed. If the infection cannot be managed with root canal treatment or retreatment, apicoectomy may be needed.
During apicoectomy, the root tip, or apex, and the infected tissue are removed. Then filling is done to seal the end of the root. An apicoectomy is performed using an operating microscope. That's why apicoectomy is also called endodontic microsurgery.
Like all medical procedures, apicoectomy too carries a few risks. The risks of apicoectomy are as follows.
However, before the procedure your endodontist take X-rays to determine how close the roots are to the nerves, and so the chances of damage are extremely small.
In most patients apicoectomies take approximately 30 to 90 minutes. The duration of the surgery varies on the location of the tooth and the complexity of the root structure. Time taken for apicoectomies of the front teeth is generally the shortest whereas lower molars generally take more time.
