Revascularization and closing perforation

MTA ( mineral trioxide aggregate ) is a particular cement which is used for treatment of endodontic complications.


Revascularization of permanent teeth, that are “dead” and have unfinished growing of its root

Teeth whose roots are still growing, but are “dead” because of some reasons (very deep caries, trauma…) have open root tip, and infected canal. To keep root growing up is needed endodontic treatment. With the first visit, the canal is heavily irrigated  with solutions for disinfection and is closed with medicament. With the second visit the medicament is removed and is provoke blooding. Is waited for few minutes for blooding to stop, and the rest of the canal is closed with MTA. Then growing of the root is traced by making 1-2 x-ray records annual.

Closing of an perforation with MTA

On the pictures is visible that post is cemented between both canals!? Regularly posts are cemented into canals, but in this case is not, and is made perforation between two canals.

To rescue the tooth, perforation is closed with MTA.

Closing of an open apex with MTA 

In this case to be rescued a tooth, apex (tip of the root) had to be closed with MTA, because it was open. Reason for that is previously made apicoectomy (surgical intervention whereby a tooth’s root tip is removed) which had not been successful.
