arsenous oxide

1. Methods 311 teeth of 293 cases which were suitable to be sealed as varied time 1~ 12 days were treated with arsenous oxide to observe the condition of pulp deactivation and percussion pain when return.
   方法对293例、311颗适合失活的恒磨牙进行三氧化三砷失活，封药时间为1~12d不等，观察根髓失活情况及患牙复诊时叩痛变化情况。
2. The experiments included both small and extended test. Because the Arsenic in secondary zinc oxide exists mainly in the form of arsenous oxide, which is volatile, the roasting method of adding reductant carbon to secondary zinc oxide is used to remove Arsenic.
   本研究实验包括小型实验和扩大实验，由于次氧化锌中砷主要以三氧化二砷形态存在，因此可以通过三氧化二砷易挥发特性，采用在次氧化锌中加入炭还原剂的焙烧方法脱砷。
