Hidden lesion (by Ilya Mer)

Русская версия

Here is the second abutment of the bridge. #24 (12) was recommended for retreatment in spite of there was no sign of PAL on preop X-rays.

But the true picture is seen on CT. There was bone resorption : both in periapical and furcal area.

One step endodontics was done.

PreOp X-rays, no PAL is seen
PAL between roots of premolar
PAL is seen only on CT
non surgical retreatment was done
