Processing the data from dental health examinations requires detailed procedures for many items. In order to use the computed data to the best advantage for regional health programs and for personal health guidance, the arrangement of our work environment to enable precise data processing is an urgent need. For this, we used to process examination data on the main computer system of the Computer Center, at the University of Tokyo. However, preparing a file for the data processing on a computer is always annoying and time consuming. Therefore, we designed here an input software to directly prepare a data file on a personal computer, and put it to trial in an actual dental health examination. We were able to file and process the examination data very quickly. The application of a computer to dental health examinations is thus very useful and helpful for further development of dental health science

To investigate the extent of oral diseases in the aged, a dental examination was conducted in combination with medical examinations of elderly inhabitants of Miyako district, Okinawa pref.<BR>Abnormal oral findings were noted in 1, 655 (29.19 %) of 5, 670 examinees.
