Suite 1, Trafalgar House
110 Manchester Rd, Altrincham, WA14 1NU

Scanner Used:
Dexis OP 3D

Clinical Information:
Large radiolucency in the mandible on the right side

Scanning Protocol:
Standard Panoramic (OPG)

Radiation Dose: 
Approximately 0.007 mSv


  • There are no obvious caries or periapical radiolucencies.
  • Normal periodontal bone levels are seen.
  • The LL8 is unerupted and horizontally impacted. The ID canal is deviated, overlapped and narrowed at LL8 roots area. The canal runs close to the LL8 crown inferior margin. The findings indicate an intimate relationship between the canal and LL8.
  • In the right ramus of the mandible there is a large, well corticated radiolucency extending from approximately 1cm below the sigmoid notch to LR8 region. There is marked expansion and extreme thinning of the anterior margin of the ramus. The upper border of the ID canal has a long contact with the inferior margin of the cyst.
  • There is another small well corticated radiolucency at the LR6 apical area. The bone texture appears to be altered at LR678 area. The LR6 distal root appears to be short and resorbed. LR7 has a normal root length with no evidence of resorption.
  • At UR1234 region, there appears to be a large corticated outline. A CBCT scan will be useful to clarify whether there is a large radiolucent lesion at this site or not.
  • The right mandibular condyle probably has a small anterior osteophyte.


  • The overall features suggest recurrent benign odontogenic cyst or tumour such as an ameloblastoma or an odontogenic keratocyst in the right mandible.
  • Another lesion is also suspected in right anterior maxilla.
  • A CBCT scan of maxilla and mandible is advised for further assessment.
  • Biopsy is also advised but preferably after the CBCT scan.

Thank you for your continued referrals.
