This is a case from 12 years ago. I re-treated all the canals including the distal which had a metal post. At, the one-year recall, the mesial root seems to have healed well. Today, I would probably have left the distal root alone and not over-enlarged those mesial canals.
This is a case from the old archives. I used to get a lot of these before 2010. I don’t see many silver cones anymore. I used to use this as a teaching case for how to remove silver cones.
This was a routine Maxillary pre-molar Re-treat. Always nice to see some anatomy being filled in the end.
