Selective Retreatment
In this case of lower 1st molar
Patient complain about pain on bitting and swelling related to lower 1st molar area
Radiographic examination reveals a periapical lesion related to underfilled distal root
And no lesion related to good filled mesial root
The patient had this RCT in 2021
Usually underfilled root canal related to periapical lesion is also under-prepared that leads to an unclean ( no disinfection) part of the canal
I decided to go for Selective Retreatment of the distal root...
Remember don't leave any GP behind ??
The Retreatment done using Videya Dental Gold files..
In RCT the difference between Success and Fauiler could be a few millimeters
