introduction: the aim of this study was to compare the diagnostic value of cone-beam computed tomography (cbct) and periapical (pa) radiography in detecting internal root resorption. methods and materials: eighty single rooted human teeth with visible pulps in pa radiography were split mesiodistally along the coronal plane. internal resorption like lesions were created in three areas (cervical,...

Digital imaging is becoming widely used in diagnostic radiology, and digital subtraction angiography (DSA) is now generally accepted [1-3]. Several studies have evaluated digital imaging using a computed radiography system for chest examinations [4-10] and for excretory urography [11] . This prospective study uses receiver operating curve analysis [12 , 13] to compare the diagnostic accuracy of...

Introduction. Does high-resolution visualization of microcalcifications improve diagnostic reliability? Method. X-rays were taken of mamma specimens with microcalcifications in 32 patients (10 malignant; 22 benign) using conventional radiography (12 Lp/mm) and high-resolution radiography (2000 Lp/mm). Histological sections were subsequently prepared and correlated to the microradiographic image...

introduction: vertical root fracture (vrf) is a common failure in endodontically treated teeth. due to vrf’s poor prognosis, a reliable and valid detection method is critical for treatment planning. conventional and digital radiographs are limited in vrf detection. recently, cone beam ct (cbct) system has been introduced. this study aimed to compare the diagnostic accuracy of these three imagin...

Secondary caries is the most common cause of dental restoration failures. This study aimed to compare the diagnostic accuracy of conventional and digital intraoral radiography and cone beam computed tomography (CBCT) for detection of recurrent caries around composite restorations. mesio-occluso-distal (MOD) cavities were prepared using bur on 45 extracted sound human molar teeth. The teeth were...

AIM To compare digital panoramic images acquired for the presurgical assessment of third molars captured with a storage phosphor-based system with conventional film panoramic radiographs. METHODS AND MATERIALS A total of 51 pairs of digital and conventional panoramic images, made simultaneously, were included in this study. The images were evaluated for diagnostic quality prior to third molar...

To assess the diagnostic accuracy of cone beam computed tomography (CBCT) in comparison with conventional radiography for vertical root fractures, 50 of 100 teeth were subjected to vertical root fracture (VRF) and then placed in dry mandibles. 3D scans were obtained for all teeth, and conventional radiographs were used as control images. All the images were assessed by 6 observers, who determin...

Background: The most often fractured bone among the tarsal bones is calcaneum. first assessment of suspected calcaneum fracture conventional radiography. modern calcaneal fractures mainly based on multidetector computed tomography, because its three-dimensional nature and Volume rendering techniques. objective this study was to compare diagnostic value Multidetector CT with Conventional radiogr...

introduction: vertical root fracture (vrf) is a complication which is chiefly diagnosed radiographically. recently, film-based radiography has been substituted with digital radiography. at the moment, there is a wide range of monitors available in the market for viewing digital images. the present study aims to compare the diagnostic accuracy, sensitivity and specificity of medical and conventi...
