Abstract:
Vertical root fractures (VRFs) in teeth without endodontic treatment are relatively uncommon. The diagnosis is based on clinical and radiographic presentations. It might be difficult to detect VRFs in non-endodontically treated molars by conventional radiographs in certain situations because of the limitations of 2D images and many others factors such as the VRFs being in their early stages. Root morphology variation and the orientation of VRFs can influence conventional radiographic detection and the interpretation of a radiolucent fracture line. The four case reports presented here describe and discuss the use of cone-beam computed tomography (CBCT) in successfully diagnosing VRFs based on direct visualization of radiolucent lines, especially those suspected from routine conventional radiographs, as well as their symptoms and clinical findings. CBCT also provides more information on the presence of VRFs.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Beams
Based on geometry, beams can be straight, tapered, or curved. Straight beams are the most common type and have a constant cross-section throughout their length. Tapered beams, on the other hand, have a varying cross-section along...
