Two well demarcated ovoid radiolucent lesions (right, 3.9×1.5 cm and left, 2.9×1.1 cm) were found incidentally in the anterior mandible of a 44-year-old female patient on her panoramic dental X-ray (). The patient did not show any symptom of radiolucencies. The radiological findings were interpreted as radicular cysts. Two fragments of tissue from the cavities were submitted for histological diagnosis. The biopsied tissue fragments showed normal salivary gland tissue with mixed serous and mucinous cells. These findings were otherwise unremarkable, except for the small amount of lymphoid cell infiltration that was discovered (). The clinical, radiological, and pathological findings were consistent with Stafne bone cavity.
A 66-year-old healthy man was referred from a private dental clinic for evaluation of a multilocular radiolucency at the left molar region of the mandible. Panoramic radiograph revealed a well-defined multilocular radiolucent area under the mandibular canal at the distal root of the second molar tooth (). The lesion showed three lobulated radiolucencies with radiopaque margins in the region of the submandibular gland fossa. On clinical examination, there was no sign of infection, fistula, or nerve damage. No history of expansion on the left mandibular angle area was recorded. The patient had no systemic disease and no specific medical history.\nCBCT scan was recommended for further study. Axial CBCT images showed a lingual bony defect located at the lingual side of the mandibular canal (). Coronal CBCT images showed a lobulated bony defect below the mandibular canal (). The maximum mesiodistal length of the defect was 14.16 mm, and the height was 7.38 mm. The maximum buccolingual length of the defect was 4.44 mm, not showing the expansion or thinning of the buccal cortical bone.\nParasagittal CBCT images showed three lobulated radiolucencies with radiopaque margins between the mandibular canal and the inferior border of the mandible (). Three-dimensional, reformatted CBCT images revealed a bony defect extending from the medial surface of the mandible ().\nThe lesion was diagnosed as a developmental salivary gland defect from the radiographic features. The patient was informed about the lesion and was scheduled for follow-up.
