Perforation repair : Middle distal canal

Subject: [roots] Perf Repair
first one in 2006. Came in for completing RCT, that has been already started by
another dentist. Medication has been CaOH2. No signs or symptoms.
After removing the existing temporary filling, it seemed as if somebody chased
the non existing middle distal canal. After C&S I first obturated the canals
( modified Schilder) and then placed the MTA (Angulus) on the perforation.
Is there any reason to first cover the perforation in a case like this?
( Perforation far away from the orifice, no bleeding) I don't like the look of
the obturation. Too much GG in the middle third. Hope it will work.

Jorg, It looks very nice. Good obturation of the apical anatomy. The perf looks
to be in the gingival 1/3, a bad place for it to be. Was there any perio
communication to the perf? That could lower the prognosis.- Randy Hedrick
Randy, No, there has been no probing more than 2-3 mm and no communication.
Because I could see the alveolar bone all around the perforation I decided to
place the MTA instead of flapping the case and try to bond the perforation
from the other side.- Jörg
