本文介绍了测量牙体组织直流电阻和交流阻抗的方法和操作步骤。测量结果说明:(1)根据牙体阻抗的变化来诊断龋齿的方法是可行的。它能识别色、形、质改变不明显的初期龋,
This article describes methods and procedures for measuring the DC resistance and AC impedance of tooth tissue. Measurement results show that: (1) According to the change of tooth impedance to diagnose dental caries is feasible. It can identify the color, shape, quality change is not obvious initial caries,
