摘要
背景:在正畸牙移动过程中,在力的作用下,牙周膜生成大量细胞因子,参与牙周组织的改建,使牙齿发生移动,牙槽骨重新塑形。热休克蛋白27就是众多参与牙周组织改建的细胞因子之一。目的:观察正畸牙移动过程大鼠张力侧牙周组织中热休克蛋白27的表达。方法:采用NiTi拉簧建立大鼠正畸牙移动模型,力值50 g。分别于加力后1,3,5,7,10,14 d取正畸牙周组织,检测热休克蛋白27在张力侧牙周组织中的表达。结果与结论:免疫荧光染色显示,正畸加力1 d,牙周组织中热休克蛋白70的表达量增强,至加力后3 d时表达量最大,之后逐渐降低,第5天时回落至初始水平。可以认为,在受到正畸力的初始阶段,即可刺激牙周组织中热休克蛋白27的表达,热休克蛋白27可能参与了张力侧牙周组织的改建。
BACKGROUND： A large number of cytokines produce in the periodontium on the tension side during orthodontic tooth movement, participate in periodontal remodeling, and make the tooth move to its normal position, thus achieving alveolar remodeling. Heat shock protein 27 （HSP27） is reported to be involved in the periodontal remodeling. OBJECTIVE： To investigate the expression of HSP27 in the rat periodontium on the tension side during the orthodontic tooth movement.METHODS： The rat models of orthodontic tooth movement were constructed using NiTi coil spring with the force value of 50 g. The periodontal samples were collected at 1, 3, 5, 7, 10 and 14 days after exerting force to detect the expression level of HSP27 in the periodontium on the tension side.RESULTS AND CONCLUSION： Immunofluorescence staining results revealed that the expression level of HSP27 in the periodontal tissues began to increase at the 1st day after exerting force, reached the highest level at the 3rd day, and then fell to the initial level at the 5th day. To conclude, HSP27 is evoked by orthodontic force early, and it may play a role in periodontal remodeling.
