Endodontics is an image-guided treatment and until the last decade, in-office
radiographic assessments have been limited to 2-dimensional (2D)
imaging technologies. However, complex anatomy and surrounding anatomic
structures can make interpretation of these images difficult.
Cone-beam computed tomography (CBCT), a variation of medical computed tomography systems (CT), uses an x-ray generator and detector that rotates around the patient to capture an undistorted 3D image. X-ray imaging, including CBCT, provides a fast, non-invasive way to visualize the teeth and maxillofacial skeleton. We only use CBCT to provide clinical information that cannot be obtained by other lower-dose imaging technologies.
More information about the appropriate use of CBCT is available from the Joint Position Statement of the American Association of Endodontists and the American Academy of Oral and Maxillofacial Radiology Use of Cone-Beam Computed Tomography in Endodontics.
We are pleased to discuss the benefits and risks of all x-ray exams with you and alternatives to the exam/s. We use radiation reduction techniques and subscribe to the size-based protocols for children advocated by the Image Gently Alliance. Please let us know if you have any questions.
