Detailed explanation-1: -Radiolucent – Refers to structures that are less dense and permit the x-ray beam to pass through them. Radiolucent structures appear dark or black in the radiographic image. Radiopaque – Refers to structures that are dense and resist the passage of x-rays.
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: -Upon detection a chemical reaction occurs. The more radiodense the material, the greater the attenuation of the X-ray beam. Bone attenuates more than soft tissue and appears radiodense (white) on a radiograph. Tissues that do not diminish X-rays are radiolucent or darker on a radiograph.
