摘要: 目的:比较5种牙本质黏结剂对人牙周膜细胞的毒性作用。方法:原代培养人牙周膜细胞,采用四甲基偶氮唑盐比色法(MTT)和浸提液法,观察5种牙本质黏结剂(Super Bond C&B、Clearfil SE Bond、G-Bond、Single Bond2、Adper Easy One)不同体积分数浸提液(100%、50%、25%)作用不同时间(24 h、48 h、72 h)对人牙周膜细胞的毒性作用。采用SPSS19.0软件包对数据进行统计学分析。结果:5种牙本质黏结剂对人牙周膜细胞的细胞毒性Super BondP<0.05),48 h与72 h无显著差异(P>0.05)。结论:5种牙本质黏结剂细胞毒性程度不同,Super Bond C&B、G-Bond和Clearfil SE Bond的细胞毒性均较轻微,Single Bond2的细胞毒性较强。

Abstract: PURPOSE: To compare the cytotoxicity of 5 different dental bonding agents to human periodontal ligament cells(HPDLCs). METHODS: Primary cultured HPDLCs were exposed to different concentrations(100%,50% and 25%)of Super Bond, Clearfil SE Bond, G-Bond, Single Bond2, and Adper Easy One for different times (24 h, 48 h and 72 h). Cytotoxicity of 5 different agents to HPDLCs were observed by MTT method. The data was analyzed using SPSS 19.0 software package. RESULTS: Cytotoxicity of 5 dentin bonding agents to HPDLCs were Super BondP<0.05)but no significant difference was found between 48h and 72h(P>0.05). CONCLUSIONS: Cytotoxicity of 5 dentin bonding agents are different. Cytotoxicity of Super-bond C&B,G-Bond and Clearfil SE Bond are weak, while cytotoxicity of Single Bond2 is the strongest among the 5 agents.

Key words: Dental bonding agents, HPDLCs, Cytotoxicity
