Would you do PET on this case?
Forty two year old woman in good health has a failing central incisor with decay in post space. Patient has been undergoing SRP's to improve soft tissues. Tooth # 9 is to be replaced with an implant. Upon seeing the CBCT I am concerned with the extent of the periapical lesion. Apical to the central it does not appear to extensive but as you move distal over the lateral the lesion increases in size. It appear to have gone through the cortical plate above the lateral as seen in the axial view. Would you do PET on this case and clean the apical lesion at the same time, maybe fill with PRF and bone. When do you feel the periapical lesion in these cases are a contraindication?
