Especially a radiolucency was seen around tooth 48. The Radiologist produced the following report upon review of the DMDI imaging: FINDINGS: 48 is horizontally impacted, crowning the distal root of 47 (Fig 1-a,1-b). The roots contact but not encircle the inferior alveolar nerve (Fig 1-c). There is a 15 x 22 x 26mm well defined nonloculated lytic lesion, lying along the buccal side of the 48 with sclerotic margins. (Fig 2-a,2-b,2-c) The Radiologist also noted: No loculation. The lesion results in endosteal scalloping and dehiscence of a 4mm segment of the inferior alveolar nerve canal(Fig 2-c, 2-d). Although statistically, a dentigerous cyst is the commonest lesion associated with an unerupted teeth, locally aggressive pathologies such as a Keratocystic Odontogenic Tumours should be considered as the likely differential. CONCLUSION: No dental erosions. No cortical breach or periosteal reaction. Mild torus mandibularis. The clear demonstration of both suspected and unidentified pathology displays the clinical importance of utilising precise CBCT imaging. DMDI provides unique, high quality dedicated CBCT scans and reconstructions with prompt imaging and report turnarounds to enhance treatment planning and help deliver optimal patient outcomes.
