摘要 目的:观察正畸牙齿移动不同时期大鼠牙髓组织中降钙素基因相关肽(CGRP)阳性神经纤维的变化。方法:采用冷冻切片和间接免疫荧光方法观察正畸大鼠牙髓组织CGRP阳性神经纤维的表达变化情况。结果:CGRP阳性神经纤维在大鼠牙髓组织中分布较丰富,在根髓呈粗大的束状;在冠髓呈条索状、串珠样,并在髓顶造牙本质细胞下层,成网状分布。正畸加力后3d大鼠牙髓CGRP阳性神经纤维数量开始增加;加力7d达到最高;至撤力后28d下降到正常水平。结论:CGRP阳性神经纤维参与了正畸牙齿移动大鼠牙髓组织的反应过程。 Objectives:To investigate the relationship between calcitonin gene-related peptide(CGRP) in rat dental pulp and tooth movement.Methods:The first maxillary molars in 36 SD rats were moved mesially by orthodontic force,18 were examined 3,7 and 14 day after application of the appliance whereas another 18 rats were observed 7,14 and 28 days after removal of the appliance respectively.6 control rats were without treatment.Then,CGRP immunoreactivity was demonstrated by indirect immunoflurescence on frozen sections of dental pulp samples.Results:3,7 and 14 days after application of orthodontic force, the CGRP containing nurve fiber counts in each pulp were 17.57±4.42,24.04±3.55 and 21±4.11 respectively,those in the control pulps were 8.03±4.49. 7,14 and 28 days after removal of the appliance, the counts were 19.23±5.23,18.23±5.08 and 8.12±5.01 respectively.Conclusions:CGRP immunoreactive nerve fibres may take an active part in tissue responses in pulp tissues during experiment tooth movement.
