Radiographs

Sensitive films that give a permanent record of relative tissue densities when they are exposed to x-ray radiation. Highly calcified dense areas of bone or tooth substance will prevent the transmission of radiation and so will show as opaque or white areas on the film. The dark areas of film indicate areas of lower tissue density.

They are used to identify any abnormalities in the teeth and gums that may need treatment.
