The digital radiographic process involves (a) the attenuation of x rays along rays forming an orthographic projection, (b) the detection of the radiation beam by a two-dimensional recording device, (c) the processing of detector signals to produce a digital image for presentation, and (d) the display of the digital image. The performance of the process is typically considered in terms of the ab...

Eosinophilic granuloma is a common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. The radiographic appearance of eosinophilic granuloma in the jaw is variable and not specific. It may resemble periodontitis, radicular cyst, or malignancies. The purpose of this report is to describe the characteristic radiographic features of eosinophilic granuloma of a 39...

Objectives: In restorative dentistry, it is essential to estimate the amount of remnant tooth structure after caries removal to make the best treatment plan. The present study was aimed to determine whether there is a correlation between the real thickness of remnant dentin under carious lesion and the radiographical measurement from photostimulable phosphor plates (PSPs). Methods: a whole numb...

The aim of this study was to evaluate whether digitized images obtained from occlusal radiographs taken with low or over dose of radiation could be improved with the aid of computer software for digital treatment. Thirteen occlusal radiographs of a dry skull were taken employing 13 different exposure times. The radiographs were digitized and then manipulated with the program for image editing. ...

The radiographic anatomy of the superior borders of pulpal chambers of primary molars was studied to clarify interpretation of superimposing cuspal images. First and second maxillary and mandibular molars were sectioned transaxially in the cervical region. The pulpal tissue was replaced by radiopaque resin before embedding the crowns in clear plastic blocks and obtaining buccolingual radiograph...
