BACKGROUND In 1951, Ardran reported that metastatic bone lesions could be detectable on plain radiography with 30% to 50% of decalcification. Authors performed experimental study for minimum level of decalcification to detect the osteolytic bone metastasis of long bone with recent technique of radiographs. METHODS One pair of fibula and humerus from two cadavers was cut into specimen 1 inch i...

One of the most important developments in field radiology is that imaging process has started to take place digital environment. The advantages radiography increase interest dentists radiography, and nowadays systems are replacing conventional systems. reasons for using fast access image, quality easy storage transmission image. Nowadays, clinicians can digitize anything recall it with patient....

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...

Background & Aims: Conventional radiography is used for the diagnosis of problems such as dental caries and failure in root canal therapy. The diagnosis accuracy of conventional radiography is acceptable in the evaluation of anatomical and pathological structures. However, it seems that by using digital radiography we can obtain more information in this field. The aim of this study is to compar...
