| Research Abstract |
The purpose of this study is clarified the influence of periodontal structure during tooth movement in young and aged. As a first step, the purpose was to examine the changes in the pulpal microvasculature following removal the opposing teeth for establishing hypofunctional condition. Our results suggest that occlusal stimulation affects the microvasculature and cellular density of dental pulp in the coronal area of teeth. As a second step, the purpose was to examine the influence of aging on the reaction of interradicular bone crest when the orthodontic force was applied to rat molar. During tooth movement, compared with young rat, the bone resorption in interradicular bone crest of aged rat is low. And aged rats were not affected by hyperglycemia condition compared with young rats under the hyperglycemia.
