| Outline of Final Research Achievements |
In the elderly who have dental treatment (group 3) with 20 or more residual teeth (group 1), no remaining dentition 20 or less (group 2), remaining number of teeth 20 or less, the extent of hippocampal atrophy and MMSE were investigated over 3 years. It was found that a group 2 had the largest extent of atrophy in the hippocampal region, followed by group 3 and group 1 in order. Similar results were seen in MMSE analysis. However, statistical analysis did not show any significant difference.
