Radiodensity (or radiopacity) is opacity to the radio wave and X-ray portion of the electromagnetic spectrum: that is, the relative inability of those kinds of electromagnetic radiation to pass through a particular material. Radiolucency or hypodensity indicates greater passage (greater transradiancy) to X-ray photons and is the analogue of transparency and translucency with visible light. Materials that inhibit the passage of electromagnetic radiation are called radiodense or radiopaque, while … Web47 Çatli: High-density dental implants and radiotherapy planning 47 Journal of Applied Clinical Medical Physics, Vol. 16, No. 5, 2015. and this may adversely affect the patient’s treatment.(2,3) Radiation scatter from high atomic number (Z) materials cause both soft and hard tissue complications in the oral cavity in head
