Region of interest
[Only visible to logged-in users]
1. Perforation of root 46D
The endodontic post in the distal root of tooth 46 has perforated the mesial surface of the root at the midroot level. A broad zone of rarefying osteitis is present in this region. In addition, rarefying osteitis is present at the mesial root apex of the tooth.
Axial views of tooth 46
These axial cross-sectional images demonstrate the perforation of the mesial surface of the distal root of tooth 46 by the endodontic post. In addition, an unfilled buccal canal is present in the distal root of the tooth.
The periapical epicenter of the rarefying osteitis at the mesial root apex of the tooth is also evident in these images.
Sagittal views of tooth 46
These sagittal cross-sectional images demonstrate the bone loss at the furcal surface of the distal root of tooth 46 adjacent to the root perforation. The rarefying osteitis at the mesial root apex is also evident in these images.
Coronal views of tooth 46
The bone loss associated with the perforation on the mesial surface of the distal root of tooth 46 drains through the buccal furcation.
2. Retained root fragments at site 48
Small retained root fragments are present within the alveolar process at site 48. No pathology surrounds these root tips, which suggests that this is an incidental finding with no clinical significance.
