Radiographic examination is one of the important clinical examinations in dentistry. Recently a great many radiographic examinations are used in the special field of dentistry. The purpose of this study was to analyze the 97, 654 radiographs (38, 414 patients) taken at the Kyushu Dental College Hospital from 1970 to 1975. The results obtained are as follows : 1. The number of annual radiographs taken increased with the increase in outpatients and the number of radiographs per patient. The number of the orthopantomographs taken is increasing yearly. 2. The number of the periapical dental radiographs decreased temporarily in 1971 but increased steadily later. This fact means that the orthopantomography is not a radiographic technique which replaces the periapical dental radiography in the radio graphic examination of the dento-maxillary region. 3. The periapical dental radiography and the orthopantomography serve different purpose for radiographic examination. The periapical dental radiography should be used for qualitative diagnosis and the orthopantomography for quantitative diagnosis.
