“…The CCD detectors halved the procedure time, but the phosphor system that was investigated increased the procedure time over that needed with traditional film. 12 More time and motion studies are needed to determine the practicality in use as well as the image quality derived from new technologies. Further, there is need for evidence-based assessment of what image qualities are essential for various dental radiographic diagnostic tasks, We need not only to produce prettier images, but also to prove that these images provide a higher standard of care and are not economically prohibitive for the practitioner or society, and that the systems promote efficient and effective workflow within the dental business.…”

Digital radiographic systems for use in dental practice have been available for almost two decades, but internationally most dentists still use analog silver halide Xray film. This article is a review of the presumed advantages digital radiographic systems have over conventional X-ray film with special emphasis on the costs and benefits of current intraoral and panoramic systems. It is concluded that more evaluations of time and motion for digital imaging in dental practice are needed. Moreover, evidence-based logic should be applied to the determination of the physical properties required by image detectors for the performance of the different diagnostic tasks that are needed when practicing dentistry.Some 90 years after the discovery of the X-ray and the first film-based dental radiographs, Mouyen conceived the possibility of using a charge-coupled device (CCD) combined with a scintillator to produce an instant image. 1 This approach is known as radiovisiography (RVG). Over the past two decades, five additional versions of RVG systems have appeared, the most recent (Kodak RVG 6000 (RVG Ultimate) and Kodak RVG 5000 (RVG Access) being based on complementary metal oxide semiconductor (CMOS) technology. More than a dozen competitors have entered the market in vending solid-state intraoral X-ray detectors (Fig.

“…Recently, several manufacturers and researchers of panoramic imaging modalities have adopted digital imaging sensors instead of a film-screen detector, such as a two-dimensional sensor with a slit, a linear sensor and a strip two-dimensional sensor. [12][13][14][15][16] These digital sensors improve the quality of panoramic images in terms of the spatial resolution and contrast resolution, but the basic idea underlying these approaches is the same as that of the conventional panoramic system with a moving film and a slit, and thus the problem in positioning patients' jaws remains and the sophisticated digital image processing availability is not possible. On the other hand, if a semiconductor detector is adopted such as CdTe connected to Complementary Metal Oxide Semiconductor (CMOS) instead of the scintillator and the charge-coupled device (CCD) detector, it is possible to achieve a new dataprocessing scheme with the help of high-speed data acquisition in the range of 300 fps.…”

“…[3,[6][7][8][9] The effective dose varies from about 4µSv to 30µSv where the variation depends on the type of apparatus used; older devices can provide a higher effective dose to the patient. Modern panoramic X-ray machines can help reduce effective dose through shielding, so that only relevant areas are exposed to X-rays [10,11]. However, during orthodontic treatment many young people undergo a number of panoramic surveys.…”

Radiological techniques based on X-rays are well established in medical diagnostics and there are known risks associated with the use of ionizing radiation like X-rays. That explains why the X-ray technology is constantly under development in the pursuit of new technologies that can contribute to reduce radiation dose to patients. Since the reduction of a radiation dose generally results in a poorer image quality, we have investigated whether the use of digital image processing can provide panoramic radiographs with enhanced image quality. An automated image processing algorithm was proposed and employed for this purpose. Panoramic X-ray examination is an important and common tool in dental radiology, used especially for children and teenagers. The technique is used to create an overview of a patient's jaw.The goal of this study is to obtain panoramic X-ray images with minimal radiation dose and sufficient diagnostic quality. A reference image acquired using the recommended parameters, were compared against 20 processed images acquired using reduced radiation dose. 20 dentists evaluated these images with respect to how well different physiological structures were shown in comparison to the reference image.The study showed that the radiation dose can be reduced by 45% without lowering the quality of the diagnostic information. Furthermore, an image with a 34% reduction in radiation dose contains more diagnostic information than the reference image.
