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.

本研究的目的是阐明牙周组织结构在年轻人和老年人牙齿移动过程中的影响。作为第一步，目的是检查牙髓微血管的变化后，删除对立面牙齿建立功能减退的条件。我们的研究结果表明，咬合刺激影响牙髓冠区的微血管和细胞密度。第二步，研究年龄对大鼠磨牙在正畸力作用下根间骨嵴反应的影响。在牙齿移动过程中，老年大鼠牙根间骨嵴的骨吸收较青年大鼠低。高血糖状态对老年大鼠的影响不明显。
