Subject: [roots] Easy retreatment
This young female patient was root canal treated on 21 and 22 back in 1997.
She sustained a trauma when she was a kid. The GP did an attempt to stop the
resorption on 21 by doing a rct, however, he could not find the canal, and
stopped in time, I think..
Patient was referred to me for advice. We recommended retreatment of 22
and monitoring 21. The location of the radiolucency was unusual.
The foramen was wide, size # 80, my rule of thumb is to use MTA if the
foramen is > 70-80. However, I could create a tapered apical prep, and was
not sure if I could pack MTA in that lateral canal. I used resilon instead.
Appeared to work out fine. - Marga
very good marga!!!! - Nuno
Nice case Marga :) is this a Lightspeed in the canal? - Hani
Thanks Hani! Yes, I always use Lightspeed (the previous version) for working
length determination and gauging the foramen when treating a tooth with a wide
foramen. Gives me a better sense of the size of the apical foramen. - Marga
