本文对大鼠正畸牙移动后Malassez上皮残留的发生率和发生率(1)、形态(2)和增殖活性(3)进行了实验研究。观察实验程序对边缘牙周膜这3个参数的影响。与压力侧和对照牙相比，压力侧玻璃化牙上皮残留物明显减少或完全消失，张力侧上皮残留物增多。结果表明，正畸牙移动产生的压力和张力都可能影响上皮残留细胞的增殖率。
An experimental study of incidence and prevalence (1), morphology (2) and proliferative activity (3) of the epithelial remnants of Malassez following orthodontic tooth movement of rat molars has been performed. It was observed that the experimental procedure influenced these 3 parameters of the marginal periodontal membrane. On the pressure side undergoing hyalinization, a marked reduction or a complete absence of epithelial remnants occurred.On the tension side, increased prevalence of epithelial remnants occurred, compared to both the pressure side and to the control tooth. The epithelial remnants appeared to be transferred from a resting into a more proliferative state.The present findings indicate that both pressure and tension produced by orthodontic tooth movement may influence the proliferative rate of the epithelial remnants.
