Hello Dr. Borksman:
I am not sure if this is what you are looking for, since it didn't cause resorption ( thank goodness ).
Personally, I have done roughly about 30 cases with the same protocol and never have seen a resorption
with sodium perborate. However I have heard that superoxol, 30% H2O2 and high concentration ( 35% and above )
of sodium carbamide sold by various companies for in-office whitening has caused root resorption when utilized
as internal bleaching.
I have attached a case involving treatment of 2 anterior teeth.
#8 received sodium perborate as a walking bleach to whiten it after the endodontic treatment was completed.
The pictures show complete coverage of the coronal extension of gutta percha with a flowable composite
before placing Na Perborate. hope this helps. - ahmad
