Question: 1 / 400

What does a radiopaque substance prevent in terms of x-ray production?

The transmission of x-rays

A radiopaque substance is characterized by its ability to absorb x-rays, which effectively prevents the transmission of x-rays through that substance. This means that when an x-ray beam encounters a radiopaque material, such as certain types of dental materials, metals, or bone, the x-rays are not able to pass through to the film or digital sensor on the other side. As a result, areas where the radiopaque substance is present will appear white or light on the x-ray image, providing contrast against surrounding tissues that are more radiolucent and allow x-rays to pass through more easily. This principle is crucial for creating clear radiographic images that can be interpreted for diagnostics and treatment planning in dentistry.
