The Community Periodontal Index of Treatment Needs(CPITN)was examined to assess the periodontal status and treatment needs in the 822 employees of two banks in Tokyo. The examined results were analyzed by using the WHO data bank. The analyzed information indicated that over 90 percent of subjects suffered from periodontal diseases in various degrees. The subjects who had periodontal pockets were found to increase with aging.
