A dental diagnostic apparatus or installation which obtains a better matching of the exposure data to the patient and has a rotary unit carrying the radiation source and the film cassette which are adjustable to an initial position by an adjustment arrangement and from this initial position the film cassette can be charged with the radiation within the framework of normal transillumination with the radiation initially beginning outside of the mandibular arch. The incoming radiation dose is measured by a detector arrangement which creates a signal that is compared in a computational unit of a control arrangement to a rated quantity corresponding to a prescribed dose value. The exposure data required from further transillumination of the patient's head are identified therefrom and the tomogram position is determined by identifying the patient-associated film speed via the jaw length/jaw width measurements and comparison to defined rated value.
