Among the remaining 411 children with negative radiographs--who were not prescribed antibiotics--5 (1.2%) were subsequently diagnosed with pneumonia within 2 weeks of the radiograph
. These five children were all under 3 years of age, but none had been treated with intravenous fluids for dehydration.
Horizontal angulation errors can occur on both film and digital radiographs
. The error can also occur with improper horizontal alignment of the receptor holding device (2).
are the first choice among imaging methods to diagnose pneumothorax correctly and rapidly.
The average time between CT and radiograph
acquisition was 123 minutes but ranged from 5 minutes to 16 hours.
It was interesting to note that there was a correlation, however not statistically significant, between the age of a patient and the likelihood of serial radiograph
Registration methods used in radiostereometry are typically feature-based, exploiting edges detected in radiographs
and a prosthesis outline obtained from the virtual model.
In this study, dental students were successful in matching a dental radiograph
of a heat-altered tooth and its original radiograph
A thorough inspection of the pre-operative radiograph
and interpretation of particular marks such as unclear view or outline of distal or mesial root contour of root canal can suggest the presence of radix cases.
A cross-sectional descriptive study was performed, 500 digital panoramic radiographs
(ratio 1:1) taken in March of 2015 at the Dental Assisting Teaching Clinic, Dental School, Universidad de La Frontera (Temuco, Chile) were analyzed.
The formula derived for evaluating skeletal age in cephalometric radiographs
is reliable and can be applied to both girl and boy subjects for legal requirements or therapeutic needs of age estimation.
Methods: The amount of residual root-filling material after endodontic retreatment procedures in 42 roots was assessed in radiographs
and in microscopic photographs of the sectioned roots by five observers.
Digitized images can be obtained either directly, by intraoral sensor or charge-coupled device, or indirectly, by scanning the conventional radiographs
and transferring them to the computer (indirect digital imaging).
