| 摘 要： | 目的：验证牙菌斑中超氧化物阴离子自由基与菌斑氧化还原电位的关系。方法：①测试菌斑氧化还原电位。②利用ＳＯＤ作为干扰因素观察氧化还原电位的变化。结果：菌斑电位低于非菌斑牙面电位，为负电位。菌斑加ＳＯＤ后使菌斑电位升高。结论：菌斑负电位与超氧化物阴离子自由基有关，自由基可能是菌斑负电位形成的主要因素。

| Abstract: | Objective: To investigate the relationship between superoxide anion free radical and redox potential in dental plaque. Methods: Redox potential in dental plaque was measured before and after addition of SOD dilution to the same spot of the plaque,the changes of redox potential were observed. Results: Negative potential was observed on dental plaque.The addition of SOD increased the potential of dental plaque . Conclusions: Superoxide anion free radical seems to play a crucial role in the formation of negative potential of dental plaque. |
