为了研究前列腺素E_2(PGE_2)、地塞米松这二种药物对正畸牙齿移动的影响,本实验选用家兔12只,分成PGE_2组、地塞米松组和对照组.除了测量各组兔牙分离距离外.还进行了透射电镜观察。实验结果表明:PGE_2能加速正畸牙移动,而地塞米松的作用相反.组织学观察三组兔牙的牙周组织超微结构未见明显的病理性改变和不良影响。本文并对PG与地塞米松对正畸牙齿移动的影响,细胞超微结构的损伤与修复以及牙周膜的透明样变性进行了初步探讨.
In order to study the effect of prostaglandin E_2 (PGE_2) and dexamethasone on orthodontic tooth movement, we selected 12 rabbits and divided them into PGE_2 group, dexamethasone group and control group.In addition to measuring rabbit teeth Separation distance outside. Also conducted transmission electron microscopy. The experimental results show that: PGE_2 can accelerate orthodontic tooth movement, while dexamethasone has the opposite effect.Histological observation The rabbit periodontal tissue ultrastructure showed no obvious pathological changes and adverse effects. In this paper, PG and dexamethasone on the orthodontic tooth movement, cell ultrastructure damage and repair and periodontal membrane of the transparent degeneration were discussed.
