1. Chronic osteomyelitis associated with impacted tooth 48
Tooth 48 is vertically impacted within the right posterior mandible. The follicle is enlarged and communicates with the oral cavity through defects in the overlying alveolar crest and within the buccal and lingual cortical plates. The surrounding alveolar process and inferior mandibular body are diffusely sclerotic around this impacted tooth, and lamellar periosteal bone formation is noted along the lingual and inferior aspects of the mandible. The crown of tooth 48 exhibits extensive intracoronal resorption, and the roots are minimally formed.
These radiographic findings suggest the presence of chronic osteomyelitis associated with the impacted tooth 48. This tooth is likely acting as a sequestrum, and extraction will be required. Note that the extent of sclerosis within the ramus is unknown based on this limited field of view.
Right mandibular nerve lingual to tooth 48
The right mandibular nerve courses lingual to the minimally developed roots of the vertically impacted tooth 48. The nerve is moderately compressed by tooth 48.
Axial views of tooth 48
These axial cross-sectional images demonstrate extensive resorption associated with the impacted tooth 48. Defects within the buccal and lingual cortical plates are evident adjacent to the enlarged follicle around the crown. Note the presence of peripheral sclerosis surrounding this impacted tooth.
Mesiodistal views of tooth 48
These mesiodistal cross-sectional images demonstrate the enlarged follicle around the extensively resorbed tooth 48, which communicates with the oral cavity through a defect in the overlying alveolar crest. Extensive sclerosis is noted around this impacted tooth. Lamellar periosteal bone formation along the inferior mandibular border is also evident.
