摘要
目的:对比分析牙周炎和健康状态下牙移动对牙槽骨的影响。方法:72只Wistar大鼠随机平分为牙周炎牙移动及健康牙移动,近中移动各组大鼠上颌第一磨牙,在规定时间点测量各组实验动物牙槽骨密度和高度并进行统计分析。结果:正畸牙移动后牙周炎组的牙槽骨密度低于健康组,差异有显著性,而两组牙槽骨高度未见显著性差异。结论:牙周组织炎症得到控制的前提下可以进行进行正畸治疗。
Objective：To compare and analysis the effect of tooth movement on alveolar bone under periodontitis and health status.Methods：Seventytwo Wistar rats were randomly divided into healthy and periodontitis tooth movement groups.We moved mesially the maxillary first molar of rats in each group,We measured alveolar bone density and height at predetermined time for statistical analysis.Results：After we moved Orthodontic tooth,alveolar bone density in periodontitis group is lower than that in healthy group.The difference was statistically significant,whereas no significant difference was found on alveolar bone height.Conclusion：Orthodontic treatment is proper for periodontal tissue only when the Inflammation is controlled.
