Abstract
The purpose of this study was to assess the role of a chemical contrast medium used in plain x ray and CBCT (cone beam computed tomography) sialography imaging in the detection of different changes associated with lesions of salivary glands. 20 subjects were recruited into this prospective clinical study over a 1 year time period. Sialography was performed by an oral and maxillofacial surgeon. A lateral skull plain image was then made and a three-dimensional scanning using a CBCT machine. The imaging volume was centred on the gland of interest. The lateral skull plain images represented the two-dimensional part of the study, and these were used for comparison with the three-dimensional investigation, the CBCT images.
