【摘要】：根管预备时,采用单纯机械预备方法无法完全去除根管内感染,化学冲洗是消除根管内感染不可或缺的步骤。理想的根管冲洗剂应具备彻底清除玷污层、润滑根管、有效杀菌、对组织无毒性且不损伤牙齿结构的特点。现有的根管冲洗剂尚不能同时满足上述所有要求。QMix是由乙二胺四乙酸(EDTA)、氯己定(CHX)和表面活性剂混合组成的根管冲洗剂。QMix能够有效去除玷污层,杀菌性强且有持续的抗菌作用,细胞毒性小且生物相容性好,对牙本质的着色浅,对牙本质微硬度的影响小。此外,QMix还可以提高根管封闭剂的润湿性且不影响其粘接性能。本文比较QMix与其他常用的根管冲洗剂(如次氯酸钠、CHX、EDTA、Smear Clear、MTAD等)在去除玷污层、对牙本质作用、对根管封闭剂的影响、细胞毒性、抗菌作用等方面的作用特点,将目前对QMix的研究成果作一综述。
[Abstract]:In root canal preparation, the root canal infection can not be completely removed by mechanical preparation method. Chemical washing is an indispensable step to eliminate the root canal infection. The ideal root canal washing agent should have a thorough decontamination layer, lubricate the root canal, and effectively sterilize the root canal. The existing root canal flushing agent cannot satisfy all the above requirements at the same time. QMix is a root canal flushing agent. QMix is a mixture of ethylenediamine tetraacetate EDTAX, chlorhexidine CHX) and surfactant. Can effectively remove the smear layer, Strong bactericidal and continuous antibacterial effect, small cytotoxicity, good biocompatibility, light staining of dentin, In addition, QMix can improve the wettability of root canal sealant and do not affect its adhesive properties. This paper compares QMix with other commonly used root canal flushing agents (such as sodium hypochlorite, EDTA, Smear ClearMTAD, etc.) in removing smear layer. The effects on dentin, root canal sealant, cytotoxicity, antimicrobial activity and so on are reviewed in this paper.
