Background - Cementoblastoma is a benign odontogenic tumour
characterized by the formation of the cement-like tissue in
relation to the tooth roots. The tumour is most frequently located
in the lower jaw and occurs predominantly in younger people.
Radiologically the cementoblastoma is characterized by a welldefined
radiopaque mass fused with one or more dental roots
and is surrounded by a thin band-shaped radiolucent zone. Histologically,
the tumour is characterized by a dense mass of cement
like acellular tissue in a fibrous stroma.
Case study - A 23-year-old girl was referred to the Department
of Oral and Maxillofacial Surgery, Aalborg University Hospital, for
orthognathic surgical treatment of a congenital jaw deformity.
Panoramic x-ray showed a well-defined radiopaque mass with
distinct root resorption of 7-, which was surrounded by a thin
band-shaped radiolucent zone. The tumour was surgically removed
together with the tooth. Histological examination verified
the diagnosis cementoblastoma. Clinical and radiological followup
after 6 months showed osseous healing with no evidence of
recurrence.
Conclusion - Cementoblastoma is a relatively rare benign tumour
and the diagnosis is made based on clinical, radiological
and histological examination. The tumour is treated by surgical
removal and the recurrence rate is low.
