Abstract: Comparing the accuracy of ultrasound and indirect digital panoramic radiography in diagnosis cystic and tumoral radiolucent mandible lesions. Ten patients aged between 12 and 50 years with jaw bone lesion were selected and consented for the study. Panoramic radiography was obtained and scanned to digital form. Measurements and provisional diagnoses of lesions were made. Preoperative ultrasound and color doppler with probe examination 12 MHz were preformed. Lesion observed for the size, contents, vascular supply and provisional diagnosis made as to whether the lesion was a cyst or tumor. Surgery was performed and histopathological investigation was made which provided the gold standard diagnosis. All measurements and findings compare and analyzed with spss 0.3 software test. Existing all lesions in panoramic radiography were significant. In areas which cortical bone was inadequate thin, ultrasound imaging was significant. In 8 cases: (6 cysts and 2 tumors) ultrasound results ware agreed with histopathological gold standard. But in two cases which cortical bone was not enough thin ultrasound could not diagnose the lesion there was no statistical difference between measurements in two techniques. Ultrasound is an established valuable diagnostic tool for lesions and is noninvasive although panoramic is able to diagnose the existing the legions but can not provide accurate information on the pathological nature of lesions.
