The category of X-ray reagents includes fixatives and pantomographic image developers, which are necessary in the process of creating X-ray images of teeth and the oral cavity. Fixatives are used to stop the X-ray image on the surface of special X-ray paper, and developers are used to enhance the image, allowing it to be read and interpreted by a dentist.

X-ray reagents are extremely important in dental diagnostics, enabling accurate assessment of the condition of the patient's teeth and oral cavity. Without their use, it would not be possible to take accurate X-rays, which would make the diagnostic process and planning of dental treatment difficult.
