There are few patients who visit dental offices with dental prevention as a main purpose at the first stage of examination. On this account, it is then important as a baseline of the dental treatment system to comprehend the actual situation of new patients. For example, what dental condition do new patients have when they visit dental offices?. “Report on the survey of dental diseases”, the field survey, has been referred to for this purpose. Member dental offices of our association have accumulated clinical information on their patients in the common protocol as a database. Therefore, I made a template for selecting data of necessary items to understand patient’s actual condition at the first visit after excluding the identifiable individual information and collected the data on patients from many dental offices effectively. This method allowed for collecting patients’data with little difficulty by area and dental office from 30 dental offices in 13 prefectures. After having sorted the data, I categorized by sex, the number of existing teeth and the agespecific degree of gingival disease progress.
