Introduction: Jaw bone lesions are common pathologic conditions. The role of ultrasonography in evaluation of the extra-osseous lesions is confirmed, however, this imaging modality is not the diagnostic routine for the intra- osseous jaw lesions. The purpose of this study was evaluation of mandibular lesions via ultrasonography. Materials and Method: A prospectively, 100 patients with intraosseous jaw lesions referred to department of radio diaganosis from Oral Surgery Department, DHIRAJ GERNAL HOSPITAL , Sumandeep Vidhyapeet Vadodara, Gujarat ,between July 2018 and June 2019. All patients had radiolucent or mixed-appearance intraosseous lesions in the mandible at time of the diagnostic process. The size of the lesions was measured by USG and then compared with CT or CBCT. Moreover, the correlation amongst the echographic patterns and histopathologic results was evaluated. Results: USG is highly sensitive and specific for odontogenic cyst , artrio- venous malformation, and ca mandible showing 100% results in diagnosis followed by radicular cyst, dentigerous cyst, and osteomyelitis showing specificity of 95.6%. Most common appearance of radicular cyst on USG is simple cyst involving root of tooth appearing anechoic and without vascularity.
