Apicoectomy Apicoectomy is one of the most common surgical procedures used to treat a periapical infection of
a previously endodonticly treated tooth. In some cases, it is the only possibility of saving a tooth, in
others it is a way to avoid replacing an existing post and crown (which is a cost benefit).Local anesthetic or general anesthesia can be used.
Once the patient is numb, the gum above the tooth is cut and reflected away. An opening in the bone,
at the site of the infection is made, allowing access to the tip of the root, where the infection presents. The tip of the
root is then cut away and a small spoon is used to clean out the infection tissue. Then the dentist will make a small cavity
preparation at the tip of the root and fill it with the special material, sealing the canal (Retrograde filling). The gum
placed back and sutured back.
root amputation Hemisection and root amputation
are the procedures that are done in multi root teeth, when the infection is present at the apex of one of the roots. Hemisection
is mostly done on the lower molars. The tooth is cut in half between the roots, the infected half of the tooth is removed
and the remaining part is treated as a single root tooth. The amputation is the surgical procedure of removing the infected root of multi-root tooth. The crown part of the
tooth is not removed, but sealed with the filling material at the amputation side.
