文题释义:
口腔黏结技术:指的是利用一定的粘接剂,将各种修复材料直接贴附于患者牙齿的缺损部位或者需要修补的牙体硬组织部位,以实现在不磨切或者尽可能少磨切自然牙体组织的情况下,对牙齿缺损或者牙齿硬组织缺损进行有效修复。
细胞毒性:是由细胞或化学物质引起的单纯细胞杀伤事件,不依赖于凋亡或坏死的细胞死亡机制。有时需要进行特定物质细胞毒性的检测,比如药物筛选。细胞毒性检测主要是根据细胞膜通透性发生改变来进行的检测,常用以下几种方法:MTT、XTT法、LDH的方法及其他酶方法(如检测上清中碱性磷酸酶、酸性磷酸酶的活性等)。

 

背景:口腔黏结材料长期与牙体组织、牙龈组织及口腔中唾液相接触,所以必须具备生物安全性、低细胞毒性或无细胞毒性等特点,保证对口腔黏膜无刺激,与人体组织接触不会发生毒性及过敏反应等。

目的:观察口腔黏结材料SuperBond C&B超级粘接剂的体外细胞毒性。
方法:取对数期人牙周膜成纤维细胞,以1.0×108 L-1的细胞浓度接种在96孔板上,100 μL/孔,常规培养24 h弃上清,分组培养:实验组加入90 μL DMEM培养液+10 μL SuperBond C&B超级粘接剂浸提液,阴性对照组加入100 μL培养液,阳性对照组加入100 μL苯酚溶液。培养72 h后,利用锥虫蓝排斥实验计算各组细胞存活率。

结果与结论:实验组、阴性对照组细胞存活率均高于阳性对照组(P < 0.05),实验组与阴性对照组细胞存活率比较差异无显著性意义(P > 0.05)。结果表明SuperBond C&B超级粘接剂无细胞毒性。

Abstract:

BACKGROUND: Because of long-term contact with tooth tissues, gingival tissues and saliva in the mouth, oral bonding materials must have the characteristics of biological safety and low or no cytotoxicity, so as to ensure no irritation response to the oral mucous and no toxicity and allergic reactions when contacting with human tissues.
OBJECTIVE: To observe the in vitro cytotoxicity of an oral bonding material, SuperBond C&B.
METHODS: The logarithmic human periodontal ligament fibroblasts were obtained and inoculated in 96-well plates with a cell concentration of 1.0×108/L, 100 μL/hole. Supernatant was removed after 24 hours of routine culture, and the specimens were grouped and cultured. 90 μL DMEM culture liquid+10 μL SuperBond C&B were added in the experimental group. 100 μL medium was added in the negative control group. 100 μL phenol solution was added in the positive control group. After 72 hours of culture, the cell survival rate in each group was calculated by trypan blue exclusion test.
RESULTS AND CONCLUSION: The cell survival rates of the experimental group and the negative control group were higher than that of the positive control group (P < 0.05), and there was no significant difference between the experimental group and the negative control group (P > 0.05). These results show that SuperBond C&B has no cytotoxicity.
