No change in size of Lumen of lesion at site 12 since prior scan
The main lumen of the lesion that is present in the anterior first quadrant has not significantly changed in size since the prior scan in July 2015 (Canaray case 88993). The current scan is shown in blue, and the prior scan is overlaid in red. The periphery of the lesion is virtually unchanged in most regions.
1. Periapical rarefying osteitis at tooth 13
The one site at which the lesion has exhibited change is in the periapical region of site 13. The red colour of the periapical region of tooth 13 in these overlaid images demonstrate an area of bone that was present in the prior scan in July 2015 that has been lost in the current scan. Periapical rarefying osteitis is present in this region, and this lesion is continuous with the larger non-healing lesion apical to site 12.
Axial views of anterior maxilla
The unchanged shape of the lesion in the anterior maxilla is evident in these images, as is the continuity of the rarefying osteitis originating at tooth 13 with the lateral border of the lesion.
Mesiodistal views of anterior maxilla
These mesiodistal cross-sectional images demonstrate the generally unchanged shape of the lesion since the prior scan in July 2015.
Buccolingual views of site 12
These buccolingual cross-sectional images demonstrate the persistent buccal defect that is present in the alveolar process at site 12. This defect remains unchanged since the prior scan in July 2015.
2. Periodontal bone loss at tooth 14MB
Tooth 14 exhibits periodontal bone loss at the mesiobuccal aspect of its buccal root. This bone loss extends to the midroot level. No periapical pathology is present.
3. Orthogonal views of rarefying osteitis at tooth 13
These orthogonal cross-sectional images demonstrate the periapical epicenter of the rarefying osteitis at tooth 13. The bone surrounding the remaining root surfaces of the tooth appears normal. No signs of root fracture present. This radiographic appearance is suggestive of the loss of vitality of tooth 13. Endodontic treatment or extraction is indicated. Note the continuity of the rarefying osteitis with the persistent radiolucent defect at site 12.
4. Loss of lamina dura at tooth 11D - No change since prior scan
The lamina dura has been lost at the distal surface of tooth 11. No changes have been observed in this region since the prior scan in July 2015. This suggests that the endodontic treatment of the tooth has been successful. No spontaneous reparative bone formation is expected at the distal surface of tooth 11, based on the serial scans acquired thus far.
