Subject: [roots] Strip perf - 2 year recall
This patient appeared in my clinic with a sinus tract and radiolucent area between mesial and distal root,
Non surgical retreatment was done by myself about 18 months before the event. While taking an old root canal
filling out MB and ML were joined by GG#3. On final the X-ray filling looked "wide" but there was no sign of
perforation: no bleeding, no sealer's puffs. So, tracing with GP leaded to furcation area.
It was clear that strip perforation on internal curve of mesial root caused that process. I decided to re-endo
this case, to localize the perforation and to seal it if possible.
After the only mesial part of cast post was removed I took out the gutta percha filling and found the perforation.
The canal was filled with calcium hydroxide for 2 weeks. The sinus tract was healed and the obturation was done
by MTA Angelus.
This week I saw the patient for 2 year recall. There was no periodontal pocket, no percussion, no pain. - Ilya Mer
