Regarding X-ray passage, radiographically they provide us with radiopaque images (clear images). Ex: teeth, bones, restorations, etc. Which of the following statements is true?
a) Revealing Solution: it is a chemical solution that converts the invisible image on the film into a visible image. It affects only the metallic silver salts that have been sensitized by X-rays, removing the halogenated element and leaving a black deposit of metallic silver on the film.
b) Fixing Solution: It has the function of dissolving the remaining silver salts that were not exposed to X-rays, removing them from the emulsion and thus permanently fixing the images produced by the developer. Another function is to harden the gelatin so that the film is resistant to abrasion and dries quickly. Developer (1min) → Intermediate washing (30s) → Fixer (3-4min) → Final washing → Drying

A alternativa correta é a letra B) Fixing Solution: Ela tem a função de dissolver os sais de prata restantes que não foram expostos aos raios-X, removendo-os da emulsão e fixando permanentemente as imagens produzidas pelo revelador. Outra função é endurecer a gelatina para que o filme seja resistente à abrasão e seque rapidamente. O processo de revelação é: Revelador (1 min) → Lavagem intermediária (30s) → Fixador (3-4 min) → Lavagem final → Secagem.
