Abstract
Miniature pH indicator electrode assemblies (e.g., 10 mm. length) are provided for wire transmission. Also provided are dental assemblies containing such pH indicator electrode assemblies. The pH indicator electrode assemblies comprise micro pH indicator electrodes, wire transmission connector plugs, and heat shrinkable plastic housings. A moisture and ion impermeate, plastic seal intermediate the housing and both the electrode and the plug prevents moisture penetration therein. Dental assemblies containing such pH electrode assemblies are useful for the continuous measurement by wire transmission of pH changes in oral cavity fluids at both specific and non-specific sites.
