Root end surgery or Apicoectomy is a micro-surgical treatment that aims at removing persistent infection at the tip of the infected root. This is an option when previous root canal treatment or retreatment has failed to eradicate the root canal infection (Fig. 01).
A microsurgical opening is made at the tip of the infected root. The inflamed tissue as well as part of the root tip is surgically removed. The process is done under a surgical microscope and the use of microsurgical instruments. (Fig. 02.)
The root end is cleansed and the space filled with a bio-compatible root end filling (Fig. 03). The removal of infected tissues at the tip of the root will facilitate the healing of the bone (Fig. 04).
