Abstract

Apparatus which enables the simultaneous continuous monitoring of pH and Eh of bacterial dental plaque as it develops on a tooth surface in an artificial mouth is described. Details of the electrodes used, monitoring equipment, and culture conditions are given. Preliminary results are given showing the Eh and pH values of plaque produced in vitro to be in close agreement with readings reported for plaque in vivo. The effect of the incorporation of 1 per cent sucrose in the medium on these parameters is reported and a distinct inverse relationship between pH and Eh recorded.

摘要

描述了一种能够在人工口腔中牙齿表面细菌牙菌斑形成过程中同时连续监测其pH值和氧化还原电位(Eh)的装置。给出了所用电极、监测设备和培养条件的详细信息。给出了初步结果,表明体外产生的牙菌斑的Eh值和pH值与体内牙菌斑报告的读数密切一致。报告了培养基中加入1%蔗糖对这些参数的影响,并记录了pH值和Eh值之间明显的反比关系。
