The successful use of radiography depends on th...

AIM To describe the lateral radiographic technique, its use and indication. BACKGROUND The clinician's difficulty in performing the correct diagnosis for some endodontic situations sometimes leads to a compromised treatment of some teeth. Considering this, an alternative radiographic technique for anterior teeth (lateral radiographic technique - LRT) may be used to help endodontic diagnosis. ...

The visible absorption spectra of Kodak X-Omat V film, which had been exposed to various doses of radiation, have been investigated to analyse the dosimetry characteristics of the film with various densitometers. Common densitometers can use fluorescent light (broad band visible), helium-neon (632 nm) or other spectra of specific bandwidth. The visible absorption spectra show a slight peak in a...

One of the problems in modelling radiographic inspections concerns the film characteristics as the last step in the radiographic modelling chain, throughout which the energy deposited by the incoming radiation is to be converted to a grey value. This conversion depends not only on the total dose absorbed by the film, but also on the radiation’s spectrum and to a lesser extent also on the incide...

PURPOSE The purpose of this study was to evaluate a modified bitewing film holder based on preschoolers' acceptance and the diagnostic quality of radiographic images. METHODS Sixty-six 3- to 5-year-old children were radiographed with the modified device. Acceptance was assessed according to their behavior during the radiographic examination and to their perception of the procedure. In only th...

objectives : optimum viewing conditions facilitate identification of radiographic details and decrease the need for retakes, patients’ costs and radiation dose. this study sought to evaluate the effects of different viewing conditions on radiographic interpretation. materials and methods: this diagnostic study was performed by evaluating radiograph of a 7mm-thick aluminum block, in which 10 hol...
