Region scanned:
UR8 to UL8

Reason for referral:
Assessment of maxilla before implant treatment

Scanner used:
CS 8100 3D

Scanning Protocol:
8×5 cm FOV, 0.15 mm voxel size, 90 kVp, 3 mA, 15 seconds

Radiation dose:
Approximately 0.07 mSv


There is apical pathology on the UR6,5,4. The UR6 buccal roots have a large apical radiolucency. The UR4 and UR5 are root treated with large apical radiolucencies and destruction of the buccal cortical plate. These are probably apical granulomas or radicular cysts secondary to chronic apical periodontitis. They are contiguous and measure 12 x 25 x 9 mm.

The right maxillary sinus floor has reactionary bone formation, almost certainly due to the chronic inflammation from the apical disease. However, there is no thickening of the sinus mucosa.

The remaining teeth have mild to moderate generalized alveolar bone loss due to stage II periodontal disease.
