Abstract
Statement of Problem: Particular attention should be paid to select the optimal combination of an emulsion solution, as different combinations of film and processing materials will produce different qualities of film and processing solution influencing the quality of radiographs with regard to visual characteristics such as density, contrast and fog.Purpose: This study was performed to determine the best combination of the two different panoramic films, Agfa and Primax with three different processing solutions (Champion, Teifsaz, and Darootasvir).Materials and Method: In this experimental study, a total of 30 films were developed in three different processing solution: (1) Champion, (2) Teifsaz and (3) Darootasvir. A skull mankan of human was used in this investigation. Unexposed films of the same batch were developed together with exposed films in order to determine the fog and base densities. After processing densities, several spots were measured with a densitometer.Results: Densitometry of films showed that there was a significant difference between mean density and contrast and fog of the two films in the three different solution (p<0.001).Conclusion: Agfa and Primax panoramic films had the best combination regarding the contrast, density and fog with Champion solution followed by Teifsaz. To use Teifsaz solution we need more resarches to reach the best quality. Key words: Panoramic film, Density, Contrast, Fog, Processing solution
