Influence of Tooth Orientation on the Detection of Vertical Root Fracture in Cone-beam Computed Tomography

CE Hours: 1.0 CE hour 

Description: The purpose of this study was to assess the influence of tooth orientation in relation to the projection plane of the x-rays on the detection of vertical root fracture (VRF) with different filling materials using cone-beam computed tomographic (CBCT) imaging.

At the conclusion, participants should be able to:

• Describe how highly dense objects of high atomic number impairs the detection of root fracture;
• Explain how patient positioning for CBCT scanning may change the formation of artifacts in the presence of intracanal materials;
• Discuss how patient positioning for CBCT scanning may affect the X-ray absorbed dose of different anatomic regions.
