background and aims. with the introduction of cone beam computed tomography (cbct) in dentistry, a question has been raised whether the technique significantly increases the diagnostic accuracy in comparison with other techniques or not. therefore, the present study was undertaken to assess the accuracy of cbct modality in detecting proximal carious lesions as compared to conventional periapica...

background cone beam computed tomography (ct) has recently become effective for oral and maxillofacial imaging. objectives the aim of this study was to assess the knowledge of dentists regarding cone beam computed tomography. materials and methods in this descriptive cross sectional study, a questionnaire regarding cone-beam computed tomography (cbct) was distributed amongst 100 dentists (gener...

introduction: a study model is a precise three dimensional replica of patient’s dentition and plays an important role in treatment planning. many digital multi-media applications have become available to the clinician and his or her staff to facilitate standard procedures in practice and management. the aim of this study is to evaluate reliability and validity of dental measurement made on digi...

parotid stafne bone defect is a very rare and infrequent variant, which is located on the buccal or lingual surface of the mandibular ascending ramus. in this paper, a case of parotid stafne defect, which was incidentally discovered during dental radiographic examination, is reported. this bone defect was observed as a lucent oval-shaped defect on the lingual aspect of the right mandibular ramu...

introdouction: the aim of this study was to compare information regarding pharyngeal airway sizes in adolescent subjects with different malocclusion classes obtained from lateral cephalograms and 3–dimensional (3d) cone-beam computed tomography (cbct) scans. materials and methods: in this prospective cross-sectional study, cbct scans and lateral cephalograms of 35 subjects, taken within one wee...

introduction: having knowledge about the anatomy of root canal system is essential for success of endodontic treatment. the present study used cone-beam computed tomography (cbct), to evaluate the prevalence of third root in mandibular first molars in a selected iranian population. methods and materials: a total of 386 cbct images from subjects referred to oral and maxillofacial radiology depar...

abstract: cone-beam computed tomography (cbct) has been accepted as a useful tool for diagnosis and treatment in endodontics. despite a growing trend toward using cbct in endodontic practice the cbct images should be interpreted carefully. this case report presents a case that showed radiolucency inside and around a tooth which was free of pathologic changes under a dental operative microscope ...

introduction: the aim of the present in vitro study was to compare the accuracy of cone-beam computed tomography (cbct) in determining root canal morphology of mandibular first molars in comparison with staining and clearing technique. methods and materials: cbct images were taken from 96 extracted human mandibular first molars and the teeth were then evaluated based on vertucci’s classificatio...

conclusion this study has highlighted the anatomical variations of npc regarding its dimension, location and morphological appearance. cylindrical was the most common shape followed by funnel-shape, hourglass, and spindle, which were the other canal shapes with less frequency, respectively. the results suggest significant relationship between npc, and gender and dental status. the influence of ...

objectives: new digital two-dimensional imaging systems are considered as an easily accessible modality for sinonasal evaluation. the aim of this study was to assess the diagnostic efficacy of digital waters’ and caldwell’s radiographic views for evaluation of sinonasal area. materials and methods: a total of 273 patients fulfilling the inclusion criteria were enrolled in this descriptive-analy...
