文题释义:
氧化锆氧化铝陶瓷复合材料:是近年来新出现的一类修复材料,多项研究显示氧化锆氧化铝陶瓷复合材料已被初步应用于组织工程研究中。相比于传统材料,氧化锆氧化铝陶瓷复合材料有较高的机械强度及韧性。
碱性磷酸酶:作为机体一种重要酶类,广泛分布于体内几乎所有重要器官,其活性可反映相应细胞向成骨方向转化的趋势,因此,检测牙周膜细胞分泌碱性磷酸酶活性具有重要意义。实验将氧化锆氧化铝陶瓷复合材料与牙周膜细胞直接接触培养,以更好的对牙周膜细胞成骨分化能力进行检测。
 
背景:氧化锆氧化铝陶瓷复合材料具有优良的抗腐蚀性、较高的强度和韧性,具有广泛的应用前景。
目的:探究氧化锆氧化铝陶瓷复合材料对人牙周膜细胞增殖、凋亡和骨诱导活性的影响。
方法:将第3-5代人牙周膜细胞分2组培养,对照组细胞常规培养,实验组与氧化锆氧化铝陶瓷复合材料共培养,培养1-5 d,MTT法检测细胞增殖,Tunel法检测细胞凋亡,免疫组织化学法检测细胞Ⅰ型胶原蛋白表达,碱性磷酸酶染色检测细胞成骨活性。
结果与结论:培养1-5 d内,两组细胞增殖、凋亡、碱性磷酸酶活性比较差异均无显著性意义;培养5 d时,两组Ⅰ型胶原表达比较差异无显著性意义;结果表明,氧化锆氧化铝陶瓷复合材料对牙周膜细胞增殖、凋亡和骨诱导活性均无影响。

Abstract:

BACKGROUND: Zirconia/alumina ceramic composite with excellent corrosion resistance, high strength and toughness has wide application prospect.
OBJECTIVE: To investigate the effect of zirconia/alumina ceramic composite on proliferation, apoptosis and bone induction activity of human periodontal ligament cells.
METHODS: Human periodontal ligament cells at passages 3-5 were cultured routinely as control group and co-cultured with zirconia/alumina ceramic composite as experimental group. After 1-5 days of culture, MTT, TUNEL, immunohistochemical detection, and alkaline phosphatase staining were used to detect cell proliferation, apoptosis, type I collagen expression and osteogenic activity, respectively.
RESULTS AND CONCLUSION: Within 1-5 days of culture, there were no differences in cell proliferation, apoptosis and alkaline phosphatase activity between the two groups. At 5 days of culture, the type I collagen expression showed no difference between the two groups. Taken together, the zirconia/alumina ceramic composite has no effect on the proliferation, apoptosis and bone induction activity of human periodontal ligament cells.
