Purpose The study aimed to evaluate QMix and silver nanoparticles (AgNPs) solution in eliminating (. ) bacteria within root canals of primary molars. Materials and methods The study sample consisted of 45 extracted primary molars, which were divided into three groups: Group 1 (control) NaOCl 5.25%, Group 2 (experimental) QMix, and Group 3 (experimental) AgNPs 4000 ppm. The root canals were sterilized within an autoclave and then contaminated with . bacteria. The root canals were irrigated for five minutes in a quantity of 3 ml using a 31-gauge irrigation needle, and then bacterial smears were taken. Results Sodium hypochlorite, AgNPs, and QMix effectively reduced the bacterial count of Enterococcus within root canals of primary molars. There were statistical differences between all groups. QMix solution showed the greatest antibacterial efficacy, then NaOCl solution and AgNPs solution. Conclusion All irrigation solutions used are effective in eliminating . . QMix can be considered a good alternative to sodium hypochlorite in irrigation root canals of primary teeth.
目的 本研究旨在评估QMix和银纳米颗粒（AgNPs）溶液在消除乳磨牙根管内（. ）细菌方面的效果。材料与方法 研究样本包括45颗拔除的乳磨牙，分为三组：第1组（对照组）5.25%次氯酸钠，第2组（实验组）QMix，第3组（实验组）4000 ppm的AgNPs。根管在高压灭菌器中进行灭菌，然后接种（. ）细菌。使用31号冲洗针以3毫升的量对根管冲洗5分钟，然后制作细菌涂片。结果 次氯酸钠、AgNPs和QMix均能有效降低乳磨牙根管内肠球菌的细菌数量。所有组之间存在统计学差异。QMix溶液显示出最大的抗菌效果，其次是次氯酸钠溶液和AgNPs溶液。结论 所有使用的冲洗液在消除（. ）方面均有效。在乳牙根管冲洗中，QMix可被视为次氯酸钠的良好替代品。
