摘要: 目的:观察芦荟膏在大鼠拔牙创愈合过程中的促进作用。方法: 60只Wistar大鼠拔除左右上颌第一磨牙,建立拔牙创动物模型,随机分为实验1和2组(30%和50%芦荟膏组,每组30只),右侧拔牙创内放入芦荟膏作为实验组,左侧常规处理(不放任何药物)作为对照组。于处理后2、4、6、8、11及15 d肉眼观察拔牙创软组织愈合情况,测量创口面积,并进行组织学观察。结果:拔牙第4天以后,实验1组和实验2组拔牙创面积与对照组比较明显缩小,差异有显著性(P<0.05),且实验1组拔牙创面积小于实验2组(P<0.05)。组织学观察可见,实验组拔牙创内新骨形成比对照组早,实验1组拔牙后15 d骨样组织填充满拔牙创,较对照组及实验2组愈合快。结论:芦荟膏具有促进拔牙创成纤维细胞增殖及肉芽组织和上皮细胞生长的作用,有利于牙槽新骨形成,促进拔牙创的早期愈合,且30%芦荟膏的作用优于50%芦荟膏。

Abstract: To evaluate the effect of basic aloe mastic on the healing process after tooth extraction in rats. Methods The models of tooth extraction wound were established by extracting the left and right maxillary first molares in 60 Wistar rats, and randomly divided into two groups. Right sides of teeth extraction socket were used as experimental groups,experimental group 1 was filled with 30% aloe mastic , experimental group 2 was filled with 50% aloe mastic. Left sides of teeth extraction socket were used as control group. The histological observation was performed after tooth extraction at 2,4,6,8,11,and 15 days. Results There was a significant difference of the wound areas between experimental groups and control group at early stage (15 d) after tooth extraction (P<0.05). The histological observation confirmed that in experimental groups, the new bone formation was earlier and quicker than that in control group. Conclusion Aloe mastic has the effect to promot the proliferation of fibroblasts and the growth of granulation tissue and epithelial cells, it is in favour of the formation of new alveolar bone effectively during wound healing of extraction at early stage. Meanwhile the effect of 30% aloe mastic is better than 50% aloe mastic.
