Dental radiographic and other imaging examinations have been taken at the Department of Dental Radiology, Kyushu Dental College Hospital. Plain radiography was found to be taken most frequently in the radiological examination. Not only tomography and contrast radiography but also ultrasonography and computed tomography could be carried out recently. The aim of this survey on the imaging examinations is to clear the role and characteristics of our department at the Kyushu Dental College Hospital. Two hundred and seven thousand eight hundred and eighty-five imaging examinations, which were taken at our department from April 1, 1985 to March 31, 1995 was analyzed mainly on the examination numbers and methods. The results were as follows : 1. The number of annual patients, who visited our department during the past 10 years, increased yearly. The number of the annual imaging examinations during the same period also increased. The results obtained suggest that there was relationship between the number of outpatients and the number of imaging examinations. Examination numbers in spring and summer were larger than those of the other seasons. 2. The periapical dental radiographs were taken most frequently, and their number occupied a half of all radiographs taken in our department. 3. Modified schuller and orbito-ramus radiographies have been carried out significantly. This phenomenon illustrates that patients who suffered from temporomandibular joint disorders are increasing. 4. Due to the beginning ultrasonography examination in our department in February 1990, contrast radiography for the diagnosis of soft tissue diseases decreased especially in 1992. 5. To evaluate the imaging examinations in our department, the examination number was compared with that of imaging examinations in the Departments of Dental Radiology, at Niigata University and at Hiroshima University. The examination number at either Dental Hospital was predominantly larger than that of our Dental Hospital. However, it was interesting that panoramic and occlusal radiographies were taken more frequently in our department than in either Dental Hospital.
