All clinical cases/Cases by Ilya Mer/Endodontics/Follow up/PAL 2014 November 7, 2014 Just wait a little bit (by Ilya Mer) Do we expect large cyst-like lesion after non surgical RCT? Yes, sure! Caliscan showed that almost 74% of these sort of lesions could disappeared if follow up was longer than usual. Patient appeared with symptoms of SAP in November 2009. Two treatment session endo was done. 1 and 3 year follow showed no sign of healing which started later. Healing is in a progress 5 years after treatment has been completed. There was no need in surgery in thas case.
