One more puzzle case which treatment plan better in this case. Surgical or non surgical?
Well, MB root looks hopeless, ledge in mid third in most cases means you can’t negotiate this canal till apex. In cases like that surgical approach can be considered as a first choice. But how about MB2? Can it be helpful to find the way to an root apex? I case you find MB2 it can work out.
So why the choice was non surgical ReTx? The access was very easy and attempt to find MB2 was reasonable. In case of final restoration already been done – surgery would be first option in my clinic.
