Radiological and clinical features of calcifying epithelial odontogenic tumour

To analyse systematically the radiographic features of the calcifying epithelial odontogenic tumour (CEOT). Clinical and radiological features of 67 cases of CEOT (four new and 63 from the literature) were analysed. There were 27 (41%) males and 39 (59%) females with a male-to-female ratio of 1 : 1....

Description
Summary:To analyse systematically the radiographic features of the calcifying epithelial odontogenic tumour (CEOT). Clinical and radiological features of 67 cases of CEOT (four new and 63 from the literature) were analysed. There were 27 (41%) males and 39 (59%) females with a male-to-female ratio of 1 : 1.5. Age ranged from 13 - 77 years (mean 43.5 years), with a peak in the fourth and fifth decades. The mandible was involved in 74% of the cases and 69% of all lesions were in the posterior area. The mixed radiolucent-radiopaque pattern was the most frequent (65%), with 32% radiolucent and 3% radiopaque. Coronal clustering of the radiopaque material was found in 12% and in one case, a 'driven snow' pattern of the radiopaque material was clearly recognizable. Lesions were unilocular in 58%, multilocular in 27% and not loculated in 15%. The unilocular type was more frequent in the maxilla than in the mandible. Borders were well defined and corticated in 20%, defined but not corticated in 59% and diffuse in 21%. Sixty per cent were associated with impacted teeth. Lesions larger than 3 cm tended to be more frequent in the mandible, mixed radiolucent-radiopaque and to have a higher proportion of diffuse borders than the smaller lesions. Radiographic features which have been considered characteristic of CEOT, coronal clustering and 'driven snow' patterns, are seen in only a small percentage of cases.
