Introduction: The study was undertaken to evaluate the practice of chest radiography using different digital imaging systems and its influence on dose and image quality.  Materials and Methods: The study was carried out in two hospitals from March 2016 to June 2016. Sixty ambulatory patients aged 21 to 60 years who were able to cooperate without difficulty and weighed between 60 to 80 kg were ...

Native rabies virus glycoprotein (RVGvir) is a trimeric, membrane-anchored protein that has been shown to interact with the p75NTR neurotrophin receptor. In order to determine if the RVG trimeric oligomerization state is required for its binding with p75NTR, different soluble recombinant molecules containing the entire RVG ectodomain (RVGect) were expressed alone or fused at its C terminus to t...

Introduction: The aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals.Methods: Thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. After access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. Wi...

objectives: this study aimed to assess the diagnostic value of conventional and digital radiography for detection of cavitated and non-cavitated proximal caries. materials and methods: fifty extracted human premolars and molars were mounted in a silicone block. charge-coupled device (ccd) and photostimulable phosphor plate (psp) receptors and intra-oral films were exposed with 60 and 70 kvp wit...

background radiography plays an important role in the detection of interproximal caries. objectives the aim of the present study was to determine diagnostic accuracy of chargecoupled devices (ccd), photo stimulable phosphor (psp) and film radiography in detecting non-cavitated caries. patients and methods seventy-two non-cavitated approximal surfaces of extracted human posterior teeth were radi...

introduction: inappropriate condensation of gutta-percha or improper use of sealer can lead to voids in root canal filling material and consequent failure of the treatment. timely detection of voids within root canal filling may prevent complications. in this study, we compared the accuracy of digital and conventional radiograph for detecting voids within root canal fillings . materials & metho...

The use of digital imaging for the diagnostic purpose has been increased during last few years. This technique has brought advancement in the field of radiography. The effect of digital imaging on workflow has a direct relation with the performance of technologists. Aim: The predestined aim of this study was to analyze the use and influence of digital imaging on the workflow of the radiologists...

In private practice, success is ensured when one balances the art, science, and business of dentistry. Advanced technology continues to expand the capabilities of the contemporary dental practice, providing tools that allow clinicians to achieve greater efficiencies and productivity. Digital radiography, as one such tool, conveys benefits such as patient safety, rapid image capture, and many ot...

Wilhelm Roentgen first discovered X-rays in 1895. Since its introduction the mid-1980s, digital radiography has surpassed traditional screen-film radiography. 2000, more than 75 percent of medical clinics United States have migrated to (DR). In fact, US government ordered that all records be converted digital. Indirect, direct, or semi-direct pictures are types currently available. Forensic rad...

introduction: external root resorption is a clinical problem that often cannot be detected clinically. thus, radiography plays a crucial role in its diagnosis. however, optimal radiographic quality with minimal radiation exposure {2.1 [en] verify english word/phrase choice} is an important factor in selecting the appropriate radiographic technique. the aim of this study was the comparison of ac...
