[Value of radiography in diagnosis of central tumours of the jaws].

Abstract

The radiographic examination is an adjunct and indispensable to the diagnosis of tumours of the jaws and is accomplished to provide images of the internal features of the tumours and the effect of the lesion on the surrounding structures. Radiographic diagnosis is the identification of a lesion based solely on observation of the radiographic features of that lesion without relying on information from any other source. This approach, however, is extremely difficult and on many occasions unreliable, because many lesions will show similar and confusing radiographic features. Consequently, it is necessary to use a more reliable and practical diagnostic approach, which is the radiographic differential diagnosis approach. In this paper presents the radiographic findings which are representative of characteristic features of the tumour and permit general categorisation of lesions. The radiographic data is helpful in these cases to categorise the general nature of the lesion as benign or malignant and the final diagnosis of such lesions is made at biopsy.
