该研究的目的是评估枸橼酸在根管冲洗中作为脱钙和清洗剂的不同性能和抗菌效果。 材料和方法 试验溶液为:0.1 mol/L(pH2.6),0.5 mol/L(pH1.6),1 mol/L(pH1.3)和2 mol/L(pH1.1)的枸橼酸溶液;0.1 mol/L(pH3～6)和0.5mol/L(pH3～6)的枸橼酸一枸橼酸钠溶液;0.5mol/L(pH7.6)EDTA溶液,另配蒸馏水作为对照。 脱钙作用的研究方法:将牙本质粉末和树脂粉按3∶1昆合,再加入0.5ml单体,然后填入聚乙烯圈(高5mm,内径9mm)。凝固后取出制作的圆盘,修整表面,表面盖一层直径6mm的纸,在盖纸外围区域的圆
The purpose of this study was to evaluate the different properties and antibacterial effects of citric acid as decalcification and cleansing agents in root canal irrigation. Materials and methods The test solutions were citric acid (0.1 mol / L, pH2.6), 0.5 mol / L (pH1.6), 1 mol / L (pH1.3) and 2 mol / L Solution; 0.1mol / L (pH3 ~ 6) and 0.5mol / L (pH3 ~ 6) citric acid citrate solution; 0.5mol / L (pH7.6) EDTA solution, the other with distilled water as a control. Study on decalcification: dentin powder and resin powder by 3: 1 Kunming, and then add 0.5ml monomer, and then filled with polyethylene ring (5mm high, an inner diameter of 9mm). After the solidification, the prepared disc was taken out, the surface was trimmed, a 6 mm diameter paper was covered on the surface, a circle
