Here another case was referred, due to generalized discomfort, with a possible suspicious maxillary osseous lesion between the roots of teeth #1 and #2. The decision was made to acquire a CBCT scan.

The coronal view clearly describes the width of the osseous medullary defect having been cloaked by the relatively thick cortical bone of the posterior maxillary alveolus.

The axial view demonstrates the periradicular nature in the apical area of the lesion.

The sagittal view also displays the apical lesion along with a view of the cortical osseous density.

The final treatment radiograph.

Please share with your colleagues. There will be weekly additional CBCT scans presented on this blog for your educational benefit.
