CLINICAL MEDICINE

Detailed explanation-1: -Structures that are cavities, depressions, or openings in bone such as a sinus, fossa, canal or foramen will allow x-rays to penetrate through them and expose the receptor. These areas will appear radiolucent or black on radiographic images.

Detailed explanation-2: -Radiolucent: It means black, dark image that’s due to penetrations of x –ray through the object to film and this can be seen in the radiographic image of soft tissue pulp, periodontal ligament. 1. Enamel: It’s, the most radiopaque structure.

Detailed explanation-3: -In the normal patient presenting to the oral and maxillofacial practitioner, the normal radiopaque structures are anatomical: the teeth, the bones of the jaws (including the middle-third of the face and nasal bones), the stylohyoid complex (including the hyoid bone), the skull base, and cervical vertebrae.

Detailed explanation-4: -The most common example of something radiopaque is the human skeleton. Bones cannot be seen through under radiation, which is why x-rays are such an effective way of visualizing bones.
