Abstract

Differentiation of fibro-osseous lesions occurring in the jaw bones is often difficult. Because the radiographic findings of these lesions are either similar or show various internal conditions over time. The present study investigated the radiographic pattern of 40 jawbone lesions classified into three groups histopathologically: tumor, dysplasia and inflammation. These three groups were also sub-divided into 5 types based on radiographic patterns: focal, target, radiolucent, calcification and multiconfluent. Then, the relationship between radiographic patterns and histopathologic findings were investigated.<br>The results demonstrated that the target and multiconfluent types were observed most frequently in the tumor and inflammation groups. There was no focal type in these groups. Although the multiconfluent type was rare, the focal type was most frequently observed in the dysplasia group. A correlation between each group and five radiographic type was shown by χ² test (p<0.05).<br>The multiconfluent type in edentulous regions showed a high incidence in each group.<br>Because of the modification of radiographical findings, radiographical diagnosis of this lesion is not easy. However, there is a high possibility that lesions showing a focal appearance are neither tumor nor inflammation.
