摘要
目的 :探讨根充糊剂不同粉液比及碘仿添加比例对封闭根管能力的影响。方法 :用毛细玻璃管模拟根管进行浸墨实验。结果 :随着粉液比例的增加 ,糊剂导入的难度明显加大 ,但根充糊剂浸墨的长度却明显缩短。随着碘仿添加比例的增加 ,根充糊剂体积收缩的程度明显加重 ,而且浸墨的长度也明显增长。结论 :2 .5∶1是根充糊剂 (上海二医张江生物材料有限公司生产 )比较理想的临床粉液调拌比例 ;
AIM:To observe the affect of different mixed proportion and iodoform additive proportion to the sealing ability of root canal sealing paste in vitro .METHODS:The capillary glass tubes was used in the dye-penetration test.RESULTS:Accompanied by increment of mixed proportion (powder to liquid), the difficulty of filling glass tubes obviously raised,but the degree of dye penetration was obviously decreased. In addition,accompanied by increment of iodoform additive proportion, not only the volume of root canal sealing paste obviously shrank, but the degrees of dye penetration was obviously increased.CONCLUSION:2.5∶1(powder to liquid) is the best mixed proportion of root canal sealing paste.1∶5 is the proper additive proportion of iodoform in root canal sealing paste.
