摘　　要：目的测试分析新型光固化正畸釉质粘接剂的细胞生物相容性。方法依据ISO国际标准Ⅲ，采用体外细胞培养四甲基偶氮唑盐比色法和倒置相差显微镜形态观察法对新型粘接剂的生物相容性进行评价。结果新型粘接剂组与阴性对照组之间光吸收值（OD）差别无统计学意义。新型材料细胞毒性为。级。结论新型光固化正畸粘接剂具有良好的细胞生物相容性。Objective To investigate the biocompatibility of a new light-cured composite enamel adhesive. Methods According to ISO-7406 criterion, MTT-assay and Inverted Microscope for the culture cells in vitro were used to evaluate the compatibility of a new adhesive. Results OD was similar to the negative control and no significant difference between the new adhesive and negative control was found. Conclusion The new light-cured composite enamel adhesive presented reliable biocompatibility.
