a. Some, but not all, of the silver halide crystals are ionized. Metal restorations absorb x-ray energy and prevent the radiation from reaching the film. Denser tissues such as enamel and bone absorb x-ray energy and prevent much more of it from reaching the film than less dense structures such as dentin or pulp.
