Densitometric evaluation of intra-oral radiographic film-processing solution combinations.

In order to determine the effect of seven film processing solutions on the quality of the radiographic image produced on three intra-oral speed group D radiographic films, an aluminium step-wedge was used as a phantom and the films exposed under standardized conditions. Processing was carried out, using each of the seven processing solutions in strict accordance with the manufacturers' recommendations. The processed films were subsequently subjected to densitometric evaluation and the data pertaining to base plus fog, radiographic contrast, density and relative film speed, for each film-processing solution combination, were tabulated. The best combination proved to be that of Flow X-ray film and Kolchem processing solution.
