Nukospot,

Okay I will re post your thread and reply in bold.

<<"#11 RCT attempted, unable to negotiate the canal due to calcification, filled with obtura. Buccal perforation repaired with MTA. Apicoectomy #11 with IRM retro-fill.">>

CALCIFICATION MEANS THERE WAS NO OPENING IN THE CANAL. SO WHAT DID HE FILL WITH GUTTA PERCHA?? BUCCAL PERFORATION MEANS HE PUSHED AN INSTRUMENT THROUGH THE FRONT WALL OF THE ROOT OF YOUR TOOTH TRYING TO OPEN UP THE CALCIFIED CANAL. SO THIS MEANS THAT BACTERIA WAS ALSO PUSHED THROUGH THAT OPENING. MTA IS MINERAL TRIOXIDE AGGREGATE WHICH IS BASICALLY STERILIZED PORTLAND CEMENT AND IT IS USED TO COVER A LIVE NERVE OR A PERFORATION OF A ROOT IN AN ATTEMPT TO HEAL THE TOOTH. IN SOME CASES MTA WORKS PRETTY GOOD BUT IT IS NEVER REALLY A CURE. IRM STANDS FOR INTERMEDIATE RESTORATIVE MATERIAL AND IT IS A ZINC OXIDE EUGENOL CEMENT. IT IS USED AS A TEMPORARY FILLING MATERIAL OR USED TO PLUG UP A SURGICAL OPENING IN THE BONE AFTER AN APICO. OBTURA IS A HEATED GUTTA PERCHA GUN USED TO MELT THE GUTTA PERCHA MATERIAL INSIDE OF THE LARGE CANALS.
