Methods The attachment rate of PDLCs was analyzed by MTT and the morphology of PDLCs was observed by florescence microscope.
方法MTT法分析牙周韧带细胞在商用纯钛表面的早期粘附 ，采用落射荧光观察细胞的粘附形态。
RESULTS: PDLCs adhered and proliferated better in MTA group than in amalgam group in microscope, while in IRM group PDLCs showed no proliferation.
结果：光镜显示，人PDLC在空白组，MTA组胶原凝胶上黏附伸展良好，银汞合金组伸展较好，IRM组细胞不伸展。
Commasie brilliant blue staining was used to study the total protein content and transmission electron microscopy was used to study the ultrastructure of PDLCs.
