Analysis of the radiographic exposure and radiographic processing in dental offices in relation to fogging

Abstract

The quality of the radiographic image depends on the correct indication of the technique, the kind of film, the time of exposure and the use of processing solutions and adequate processing places. Radiographic fogging can appear in errors related to time of exposure, deteriorated films and in the radiographic processing. The aim of the present study is to verify conditions of radiographic exposure and processing in relation to fogging in dental offices. The films were exposed under standardized conditions in one phantom and, with the purpose of evaluating the radiographic processing, were processed in dental offices. Later, radiographic films were exposed, in routine, by the dentists, in their X ray devices with the usual time of exposition. After, these exposed films were processed, in an automatic processing machine. After the attainment of the radiographies, had been made readings of the optic densities (D.O.) in the lead area. It is ended that of the appraised dental offices, almost half radiographies evaluated has presented fogging as for the radiographic exposure and none presented fogging as for the radiographic processing.
