Background: Calcifying epithelial odontogenic tumour (CEOT) also known as Pindborg’s tumour is a relatively rare odontogenic neoplasm of epithelial derivationthat constitutes about 0.4-3% of all intraosseous odontogenic tumours.Objectives: To document all cases of CEOT encountered in five tertiary centres in Nigeria and their clinical, radiologic and histologic characteristics.Design: A retrospective study.Setting: Tertiary Dental Facilities in Lagos, Ibadan, Ife, Port Harcourt and Zaria (all in Nigeria) were involved in the study.Subjects: All odontogenic tumours (OTs) in the period from 1970 -2014. Case file records and biopsy reports were retrieved from the records of the five Teaching Hospitals, to obtain age, gender, location, size, clinical symptoms, pathological reports and radiographic description.Results: Out of a total of 1369 OTs, 20 (1.5%) cases of CEOT were reported. CEOT had a male to female ratio of 1.9:1, with mandible: maxilla ratio of 1.5:1 and the most common location being the premolar /molar region in the mandible. Nine (45%) cases appeared radiolucent while 11(55%) cases had mixed radio density. The mean diameter for mixed radio-dense lesions (4.83±2.99) was higher than that for radiolucent lesions (2.75±1.17) and the difference was statistically significant (p=0.049).Conclusion: CEOT is a rare tumour representing 1.5% of OTs. CEOT presents with some subtle geographic differences in its demography, however, further studies are required to investigate if these differences are coincidental or genetically determined. |
