摘要:

目的探讨骨保护素(OPG)及其配体(OPGL)在炎性牙周条件下参与牙移动及牙周改建的机制。方法采用原位杂交法检测牙周炎大鼠磨牙移动过程中OPG及OPGL在牙周组织内表达情况。结果牙周受压后,牙周炎大鼠加力组OPG及OPGL mRNA的阳性信号强度与牙周炎大鼠对照组比较,差异有统计学意义,其平均光密度值在2 d组中两者均达到峰值。结论OPG及OPGL在炎症及正畸力联合效应下的牙周改建中起着重要作用。

Abstract:

Objective To explore certain principle of how osteoprotegerin(OPG) and osteoprotegerin ligand(OPGL) take part in the periodontal tissues remodeling under the combined influence of inflammation and orthodontic force. Methods The positive signals of OPG and OPGL mRNA were measured with in situ hybridzation after orthodontic tooth movement in the experimental periodontitis groups and control ones. Results The OPG and OPGL mRNA expression intensity in the experimental group showed difference from control. All their optical density index reached a peak in day 2, respectively. Conclusion OPG and OPGL play important roles in the periodontal reconstruction induced by inflammation irritation and orthodontic force, and complex interaction could exist between the two factors.
