background and aims. the imaging techniques commonly used for foreign body detection include plain radiography, xeroradiography, computed tomography (ct) scans, magnetic resonance imaging (mri) and ultrasonography. the aim of the present study was to compare cone-beam computed tomography (cbct) with conventional ct scan in determination of the exact location of a foreign body in the maxillofaci...

introduction: the present study was conducted to assess the morphology of mandibular canines using cone-beam computed tomography (cbct) in a north iranian population. methods and materials: for the morphological assessment of mandibular canines, 150 cbct images taken from patients for different reasons were used. the mandibular canines were examined in sagittal, coronal and axial dimensions. th...

objectives: differential diagnosis of bifid mandibular condyle (bmc) is important, since it may play a role in temporomandibular joint (tmj) dysfunctions and joint symptoms. in addition, radiographic appearance of bmc may mimic tumors and/or fractures. the aim of this study was to evaluate the prevalence and orientation of bmc based on cone beam computed tomography (cbct) scans.   materials and...

objectives: the aim of this study was to assess the effect of tube current, kilovoltage peak (kvp), metal type, and the position of metal objects on metal artifacts in cone-beam computed tomography (cbct) images. materials and methods: titanium and cobalt-chromium rods were fabricated and placed in a dry human mandible. samples were scanned using a promax 3d cbct unit with different milli-amper...

introduction: due to the complexity of facial asy-mmetry, the diagnosis of different aspects of asymmetry via conventional radiographs is not precise. in this study, we investigated findings of facial asymmetry by using cone- beam computed tomography (cbct) images. materials and methods: in this descriptive study, we evaluated cbct findings of 18 patients i.e. a group of 14 females and 4 males ...
