1 = Intraoral radiographs should be considered for the evaluation of endodontic patients.

2 = Limited FOV CBCT should be considered when there are nonspecific clinical signs or symptoms with an untreated or previously endodontically treated tooth.

CBCT imaging has increased sensitivity in the detection of periapical pathosis (Figure 2.1) compared to intraoral radiographs. In the presence of clinical signs with the absence of intraoral radiographic findings, a CBCT may be recommended to rule out or rule in possible periapical pathosis. It is important to thoroughly check all of the teeth on a scan because early periapical pathosis has been noted on CBCT prior to detection on intraoral radiographs. Sagittal and cross‐sectional views are the recommended views for detecting periapical pathosis.
