Comparative Study of root canal sealing of three kinds of paste

Objective To compare the zinc oxide-eugenol paste,vitapex paste,and cortisomol paste root canal filling after root canal wall and apical region microleakage and evaluate three kinds of root canal filling paste for root canal filling when the apical root canal wall and the closure of the performance area.Methods To use three kinds of root canal filling paste filling from a single root canal teeth,the dyeing,Katagiri,measuring dye liquor from the root tip and root canal wall penetration length.Results The comparison of dye liquor from the length of apical microleakage infiltration values,cortisomol paste group microleakage values lower than the length of zinc oxide-eugenol paste group (P0.001),vitapex paste group was lower than zinc oxide-eugenol paste group (P0.001),cortisomol paste group of micro-leakage values lower than the length of vitapex paste group (0.02 P0.05); contrast dye liquor from the root canal length of wall penetration microleakage values,cortisomol paste group of micro -leakage length of the value lower than the zinc oxide-eugenol paste group (P0.001),vitapex paste group was lower than zinc oxide-eugenol paste group (P0.001),cortisomol paste group of microleakage length of the value of less than vitapex paste group (0.01 P0.02).Conclusion Cortisomol closure properties of paste of the root canal in terms of apical or root canal wall are better than vitapex paste and zinc oxide eugenol paste,vitapex paste of the root canal seal performance was better than the traditional zinc oxide-eugenol paste agent.
