by producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (cbct) systems have met many of the limitations of conventional radiography. these systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. t...

a definitive diagnosis of vertical root fracture (vrf) is often a challenging task for clinicians. this is because two dimensional periapical radiographs are usually unable to detect the fracture line due to the direction of the x-ray beam. this report presents a set of 3 cases of endodontically treated teeth that were diagnosed with vrfs based on findings from clinical, radiographic, and cone-...

objective: the knowledge of anatomic landmarks’ positions, including inferior alveolar nerve’s canal, is crucial for dentist, who has to master it. it is important to know the exact location and anatomic variety of this canal for different procedures of mandibular surgeries. the aim of the present study was to evaluate inferior mandibular canal’s anatomic position by cone-beam computed tomograp...

objectives: this study sought to evaluate the accuracy and errors of linear measurements of mesiodistal dimensions of kennedy class iii edentulous space using cone beam computed tomography (cbct) in comparison with clinical measurements. materials and methods: nineteen kennedy class iii dental arches were evaluated. an impression was made of each dental arch and poured with dental stone. the di...

introduction: conventional methods for diagnosis of external root resorption (err) are based on clinical findings and x-ray observations which are not appropriate for early diagnosis. the present study assessed the effect of different sizes and field of views (fovs) in the diagnosis of simulated external root resorption by cone-beam computed tomography (cbct). methods and materials: in this dia...

background orientation of the stylohyoid complex (shc) may be important for evaluation of the patient with orofacial pain or dysphagia. objectives our purpose was to assess the length and angulations of shc using cone beam computed tomography (cbct). patients and methods in this study, 3d images provided by cbct of 69 patients (36 females, 33 males, age range 15-77 years) were retrospectively e...

we report a rare case of a two-rooted maxillary central incisor, stressing the importance of three-dimensional imaging in treatment planning and conservative approach of management. endodontic treatment of this central incisor was carried out with a successful outcome.

background radiography is as a part of periodontal examination. early detection of periodontal disease is important in the prevention of tooth loss and patient’s general health. objectives the objective of this study was to compare diagnostic accuracy of cone-beam computed tomography (cbct) with digital direct intraoral radiography, in assessment of periodontal osseous lesions. materials and me...

introduction: this study aims at examining the difference of pharyngeal airways in patients with different occlusion postures, hoping to im prove diagnostic methods and provide a stable treatment plan for orthodontic patients. materials and methods: the data were ga-thered through cbct radiographies of patients from a specialized center for radiology. in each occlusion group according to the pe...

introduction: panoramic view as a routine dental radiograph has an important role in diagnosis of other facial abnormalities accompanied with dento- alveolar structures. in this case presentation, we discuss this subject and also the efficacy of cone-beam computed tomography in localization of foreign body in complex anatomy of nasal cavity.
