CE Hours: 0

Course Description:

A vertical root fracture (VRF) is the modern dentist's clinical dilemma; it is elusive to diagnose and notoriously known for its very poor prognosis. Because of the limitations of conventional radiography, the application of high-resolution cone beam computed tomography (CBCT) imaging in detecting VRF has generated considerable interest. However, the generated image is one of the most difficult to interpret because of the presence of imaging artifacts that may obscure the putative fracture plane. Consequently, the ability of CBCT to detect VRFs in endodontically treated teeth is an important clinical question to address. The purpose of this presentation is to critically appraise the best clinical research available to demonstrate the diagnostic ability of CBCT in detecting VRFs in endodontically treated teeth.

At the conclusion, participants should be able to:

  • Describe the required steps in critical appraisal skills of diagnostic studies.
  • Evaluate the diagnostic ability of CBCT in detecting VRF in endodontically treated teeth.
  • Describe the probability that the interpretation of presence or absence of VRF is correct given the relationship between VRF prevalence and the CBCT predictive values.
