CBCT (Cone Beam Computed Tomography)

Cone beam computed tomography is an innovative imaging technique that provides endodontists with three-dimensional views inside of the patient’s tooth. A CBCT greatly enhances the endodontist’s ability to diagnose, evaluate and treat complex canal anatomy, canal pathology and get a clearer idea of the internal anatomy of a patient’s tooth before treatment is initiated.

During a CBCT scan, the machine rotates around the patient, capturing images using a cone-shaped X-ray beam. These images are then used to construct a 3-D representation of the patient’s teeth, oral and maxillofacial region (mouth, jaw and neck), and ears, nose and throat.

CBCT images are taken when there are complex endodontic conditions, such as:

  • Root Canal system anomalies & to determine root curvature
  • Diagnosis of dental root infections in patients who present with nonspecific clinical signs and symptoms or no evidence of disease visible in conventional imaging.
  • In cases where anatomic superimposition of roots
  • To assess prior treatment complications, such as overextended root canal obturation material, separated endodontic instruments, calcified canal identification and localization of perforations.
  • Diagnosis and management of dental trauma, especially root fractures, luxation and/or displacement of teeth, and alveolar fractures.
  • Presurgical case planning to determine the exact location of root apex/apices and to evaluate the proximity of adjacent anatomical structures, such as nerves.
