摘要
目的 研究使用银汞合金粘接剂对银汞合金边缘微漏的影响。方法 应用染料渗入法 ,在离体牙上观察银汞合金在应用与不应用粘接剂的条件下的边缘微漏。结果 在银汞合金充填以前 ,应用银汞粘接剂渗漏及渗漏程度减轻 ,统计分析差异有显著性。结论 应用银汞合金粘接剂可以减小微漏 ,增强银汞合金密合度。
Objective To study the effect of Super D liner Plus Ⅱ on dental amalgam marginal microleakage.Methods Dye penetration method was used to observe marginal microleakage with or without Superbond on teeth in vitro.Results Superbonding agent might significantly decrease the incidence of microleakage.Conclusion Super D liner Plus Ⅱ bonding agent can enhance the marginal adaptability of dental amalgam.
