Cone Beam Computed Tomography

​

CBCT (cone beam computed tomography) is three dimensional imaging that has revolutionized many aspects of dentistry over the last two decades.  The scans give the highest image resolution and are extremely accurate. They are free of magnification and distortion commonly associated with regular x-ray images. These 3D images help the doctor analyze the orientation and position of critical structures like nerves, roots, previous dental work, the sinus and the nose.  CBCT requires a minimal amount of radiation. The “small field of view” significantly minimizes radiation exposure to the patient.

 

The use of CBCT is becoming more prevalent in dentistry and the standard of care for: most retreatments (root canal redo), root surgeries and treatment of resorption (a type of root deterioration).  In our practice we have utilized CBCT technology on a daily basis over the last six years. It has been an eye-opening experience.  Our team has come to appreciate its many applications and benefits in the speciality of endodontics.

 

With the use of CBCT our understanding has evolved regarding its advantages beyond the typical scenarios.  Following are some examples:

 

• Predictable treatment decision (whether to perform a re-treatment, endodontic surgery, extraction or monitoring only)

 

• Understanding the regional anatomy such as the sinuses, main nerves and blood supply in relationship to the tooth to be treated

 

• Studying the shape of the tooth and roots before treatment assists with:

  • Locating and treating all canals that would typically be difficult to find

  • Decreasing treatment time

  • Preservation of of tooth/root structure

  • More precise measurement of the roots

  • Decreasing overall radiation exposure to our patients by eliminating many of the regular dental x-rays needed before, during, and after treatment

 

• Diagnosis of the condition as it relates to:

  • Possible root fracture

  • Periodontal (gum) conditions

  • Savebility of the tooth

  • Early diagnosis of root disease and infection

  • Bone loss patterns

 

• Obtain “baseline”  imaging that can be used for comparison to future CBCT to evaluate healing or to evaluate changes.

 

We feel strongly that using CBCT technology actually saves our patients overall time and resources.  It shortens treatment time, increases success rates, eliminates unnecessary procedures, and reduces the initiation of treatment on teeth with less favorable prognosis. During the consultation visit, our team will discuss and educate our patients regarding the benefits and risks of this imaging. Recently, we significantly reduced our fee for the CBCT.  Our goal is to increase accessibility to this valuable procedure and ease the cost to our patients.
