Dental radiographs are commonly called X-rays. the bitewing view shows the crowns and interproximal areas of the maxillary and mandibular teeth If the patient is in a wheelchair, does not have the use of his or her upper limbs, and a film sensor holder cannot be used to stabilize the film sensor, you should ask the patients caregiver to assist in holding the film sensor Dentists use radiographs for many reasons: to find hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor. The radiograph should be of sufficient diagnostic quality, and keep the radiation dosage as low as reasonably achievable (ALARA). moving or lying in the same plane, always separated by the same distance.
