This study investigated the frequency of X-ray exposure among patients in an orthodondic office and compared findings to previously reported results in the Orthodontics Department of Fukuoka Dental College Hospital. This survey involved 109 patients visiting the orthodondic office to complete their treatment between March 1984 and February 1992. The results were follows : 1. The mean age at first examination in orthodindic office was 14. 3 years old, which was approximately 5 years older than of patients visiting the dental college hospital. 2. The mean period of the treatment in the orthodondic office was 3.6 years, which was approximately 2.5 years shorter than that of those treated in the dental college hospital. 3. Crowding predominated at the orthodondic office, while reversed occlusion was more common at the dental college hospital. 4. Patients underwent 3.2 panoramic radiographs and 4.5 cephalometric radiographs (1.3 posteroanterior radiographs and 3. 2 lateral radiographs) per person in the orthodondic office, while 7.1 and 15.0 (3.3 and 11.7) in the dental college hospital.
