Use of cone-beam computed tomography in endodontics Joint Position Statement of the American Association of Endodontists and the American Academy of Oral and Maxillofacial Radiology.

INTRODUCTION The American Association of Endodontists (AAE) and the American Academy of Oral and Maxillofacial Radiology (AAOMR) have jointly developed this position statement. It is intended to provide scientifically based guidance to clinicians regarding the use of cone beam computed tomography (CBCT) in endodontic treatment as an adjunct to planar imaging. This document will be periodically revised to reflect new evidence. Endodontic disease adversely affects quality of life and can produce significant morbidity in afflicted patients. Radiography is essential for the successful diagnosis of odontogenic and non-odontogenic pathoses, treatment of the pulp chamber and canals of a compromised tooth, biomechanical instrumentation, evaluation of final canal obturation, and assessment of healing. Until recently, radiographic assessments in endodontic treatment have been limited to intraoral and panoramic radiography. These radiographic technologies provide two-dimensional representations of three-dimensional tissues. If any element of the geometric configuration is compromised, the image can demonstrate errors. In more complex cases, radiographic projections with different beam angulations can allow
