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.
