In the present process the positive printed from the negative of violet-blue sensation is coloured yellow by means of a solution of auramine in the presence of basic aluminium acetate. The positive, after printing, is treated with a solution of potassium ferricyanide, potassium iodide, and ...
Moreover, the addition of 5% GSH to the SDF solution may have a minor impact on the remineralisation potential of SDF. The application of KI after SDF reduces discolouration and does not affect the expected remineralisation process.Cmert, H....
