There are extremely few reports on the results of the of maintenance care (regular dental checkup and regular debridement of subgingival biofilm). Therefore, in order to initiate a study on the relation of maintenance care of adults to the number of tooth loss, 15 dental offices investigated their patients over 40-years (2,869 patients receiving continuous maintenance care for over 5 years with the latest inspection date after September 1, 2005) on the age, the number of caries found at the first examination, the number of existing teeth at the first examination, the degree of periodontal disease progress, the number of remaining teeth at the first treatment and in the most recent visit, the number of tooth loss during maintenance care, and the period of maintenance care. The results showed that the average number of tooth loss per 10 years of maintenance care in 10 -15 years were 0.19 ± 0.499 in 40s, 0.81 ± 1.331 in 50s, 1.11 ± 1.469 in 60s and 1.53 ± 2.172 in 70s.
