CBCT - Cone Beam Computed Tomography

The most common form of dental radiograph (or x-ray) is the 2D digital image. Although 2D imaging helps detect many dental conditions, because it involves mainly hidden anatomy, endodontic diagnosis benefits by using higher-quality images.

High-resolution, focused-field 3D imaging was introduced in 2008. Realizing the game-changing nature of 3D imaging in endodontics, Dr. Anderson brought this technology to his practice in 2009. He was the first endodontist in Indiana to acquire 3D cone beam CT technology. Skilled use of this imaging has revolutionized the diagnosis and treatment of complex endodontic conditions.

What advantages does this type of imaging provide?

The advantage of 3D imaging over regular dental radiographs is the ability to view all three planes of the area in high resolution, producing a three-dimensional image that can be rotated, sliced, and enlarged. It allows Dr. Anderson to accurately visualize internal tooth and jaw anatomy so that he can identify the problem, determine the prognosis, and plan treatment. Ultimately, this highly accurate diagnostic and treatment-planning tool helps to determine the best course of treatment for the most successful long-term outcome.

How is the scan performed?

CBCT scans are performed in our office. Dr. Anderson and your referring dentist will determine the area to be scanned. The assistant will escort you to the x-ray area. You will need to remove any jewelry, glasses, dentures, partial dentures, hearing aids, or other items that might interfere with the scan. The machine has an “open design” so you will be in a standing position, similar to the panoramic scan that you receive at your general dentist’s office that takes full-mouth x-rays. The assistant will position you for the scan. The scan only takes 20 seconds to complete.

After the scan is taken, Dr. Anderson will read the images and speak with you about his findings and your future treatment options. You may be given a CD copy of the scan.

How much radiation will I receive from having this scan?

The CBCT scan’s radiation is similar to that of four bitewing radiographs by your general dentist.

What will this scan help Dr. Anderson diagnose?

  • Infection size and location
  • Canal anatomy & untreated canal space
  • Fractured roots
  • Resorptive defects
  • Trauma effects
  • Procedural errors
  • Developmental defects

It can also serve as a presurgical guide, giving Dr. Anderson a clear picture of the site and what needs to be done before he begins an endodontic surgical procedure.

Will this scan be covered by insurance?

Unfortunately, insurance coverage often lags behind technology. We will work to the best of our ability to obtain the maximum benefits from your insurance carrier, whether we are in network or considered out of network. Payment will be due at the time services are rendered. We will file a claim with your dental and medical insurance company on your behalf for payment reimbursement.
