  1. EO 005.06 Normal Intraoral Radiographic Anatomy UNCLASSIFIED//REL TO NATO/ISAF

  2. Radiographic Density • Radiopacity – light on film • Radiolucency - dark on film

  3. Radiopaque vs. Radiolucent • Radiopaque: refers to a light area on the film • Structures that are absorbers of x-rays block the x-rays from reaching the film • The x-rays are attenuated (decreased in intensity) by absorbing structures • Fewer radiation reach the film • Dense structures are strong absorbers

  4. Radiopaque vs. Radiolucent • Radiolucent: refers to a dark area on the film • Structures that are less dense are poor absorbers and allow more radiation to reach the film

  5. Radiopaque vs. Radiolucent • Enamel • Cementum • Dentin • Bone • Muscle • Fat • Air Restorative and surgical materials have various densities and abilities to absorb. Metallic materials are more dense than enamel, thus appear very white on radiographs
