Differences in Healing of a Horizontal Root Fracture as Seen on Conventional Periapical Radiography and Cone-Beam Computed Tomography

Figure 2

Digital periapical radiographs. (a) Radiograph immediately after MTA obturation in coronal root fragment (June 2013) illustrates approximately 0.5 mm extruded MTA at the apical end of the coronal fragment and a suspected fracture line at the level of the cervical third on the distal aspect of the root (arrow). (b) Radiograph one year after MTA obturation (June 2014) reveals the ingression of bone into the diastasis from both mesial and distal aspects of the fracture, but it does not fill the central aspect of the diastasis (asterisks). The apical root fragment has a continuous lamina dura without apical radiolucency. ((c) and (d)) Radiographs two years after MTA obturation (June 2015) show complete healing at the diastasis (asterisks). A radiolucent line at the distal aspect of the cervical third of the root is still noticed (arrows).
