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 conventio...
The purpose of the study was to compare the segmental measurement tool from the Shick Technologies CDR digital system with the conventional film radiography measurement technique to determine preoperative working length. Natural extracted human teeth with varying degrees of root curvature were used. All teeth were imaged using the Shick Technologies CDR direct digital system and conventional E-...
The aim of this study was to compare the accuracy of the Radiovisiography (RVG) with conventional Radiographic in canal length estimation in vitro for root canal treatment. Forty-single-rooted teeth were endodontically assessed and working lengths were determined using both conventional intra-oral dental film and Radiovisiography (RVG) 1R1X 70 intra-oral x-ray system. Measurement assessment was...
OBJECTIVES The diagnosis of root fractures by conventional radiographs is still difficult because of limitations of 2D images. Cone-beam volumetric tomography improves the diagnosis capacity in dentistry, such as increased radiation dose to the patient and presence of artifacts on the image. STUDY DESIGN This study compared the images obtained on conventional periapical radiographs and 3D sca...
While recent advances in radiologic imaging have focused on CT and MRI technology, progress in digital radiographic techniques has also had significant impact on our ability to evaluate cardiothoracic disease. A number of publications have established the improved image quality of digital imaging systems over conventional film techniques [1]. While image quality has clearly improved with digita...
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...
o bjectives: correct determination of working length is an important step for suc- cess of endodontic therapy. conventional radiography has limitations in providing the accurate location of apical foramen. for this reason, electronic apex locators (eals) were developed to shorten the treatment time and decrease the radiation dose. the aim of this study was to evaluate the accuracy of root zx ea...
