The effect of a root canal filling material on the level of lead in blood of rhesus monkeys was examined by anodic stripping voltometry. Blood-lead levels after root canal treatment with N2 cement were elevated when compared to preoperative controls. Lead 210 was incorporated into the leadfree N2 cement to identify the source of lead. Analyses of blood samples for 210Pb indicated that the lead originated from the filling material.
采用阳极溶出伏安法检测了一种根管充填材料对恒河猴血铅水平的影响。与术前对照组相比，用N2水泥进行根管治疗后的血铅水平升高。将铅210掺入无铅的N2水泥中以确定铅的来源。对血样进行210Pb分析表明，铅来源于充填材料。
