Which would be described as radiopaque? a. skin b. muscles c. sinuses d. teeth

Teeth are considered radiopaque because they contain a high level of minerals, particularly calcium and phosphate, which block X-rays and appear white or light on radiographic images. This property allows dentists to identify issues such as cavities or fractures more easily. On the other hand, skin, muscles, and sinuses are generally less dense and appear darker on X-rays, indicating that they are more radiolucent. Understanding these properties can help in diagnosing various conditions within the body effective using imaging techniques.
