Leading Minds: An Anatomy Of Leadership book.An initial comparison of digital and conventional radiography in pedodontics.
There is an increasing use of digital radiography in orthodontics and paediatric dentistry. This study compared the cost, radiation dose, image quality and technical factors of using a portable electronic radiography system and a conventional screen-film system in paediatric dentistry. In vitro digital radiographs and conventional radiographs were compared in terms of the number of projections, film exposures, beam hardening (Hounsfield units) and image resolution. A paired t-test was used for the statistical analysis (alpha = 0.05). A portable electronic radiography system (AD1000 In-Office System; Airo Industries) was used for all radiographic examinations, while conventional radiographs were obtained by using standard dual-head x-ray units. Three factors can affect the cost, dose and image quality: the imaging device, the quality of the image and the system exposure. The exposure time for the screen-film system was 17.2+/-1.9 s, while for the electronic system it was 4.0+/-1.5 s. With the standard dual-head x-ray units used, the dose-area product (DAP) of the screen-film system was 1130+/-415 mGy*cm(2), while with the portable electronic radiography system it was 150+/-44 mGy*cm(2). When this system was used with the standard orthopantomograph x-ray (OPT-XC), the dose-area product of the portable electronic radiography system was 586+/-210 mGy*cm(2). For the two systems, the quality of images and image resolution were very similar. The portable electronic radiography system offers the same image quality, as well as lower radiation dose and lower cost. Portable electronic radiography has the potential to replace conventional screen-film and fluoroscopy in paediatric dentistry.Hundreds of protesters in Baghdad have held a demonstration denouncing the US occupation of Iraq.
The protest was called by the Iraqi Communist Party, but also involved members of the outlawed Baath party, which was toppled by US forces in 2003. 0b46394aab
