Abstract

Radiographs are the pictures produced by X-rays coming in contact with an appropriate film, in a similar manner to the production of photographs by light rays. They are sometimes referred to as roentgenographs. Dental radiographs are taken by passing X-rays through the teeth and jaws and recording the resultant shadow on an X-ray film. Radiographic exposure techniques are warranted for an accurate diagnostic and treatment procedures. The dental specialist should be able to appropriately position the patient, the tube head, and the X-ray film for intraoral or panoramic film exposures. Dental radiographs are made on intraoral film which is made with the film held in the mouth during exposure. They are taken by keeping the film in closer contact to the object, hence it gives more detail in comparison to the extraoral radiographs, which are taken from outside your mouth and possesses less superimposition of shadows. Production of X-rays, types of intraoral radiography films, and protection of the patient and the operator are the topics discussed in this chapter.
