A sensor system for diagnosing dental conditions includes a sensor unit (10) which is in contact with an oral fluid such as saliva or gas, and which is operative to provide detectable signals indicative of at least two of hydrogen ion concentration, hydroxyl ion concentration, calcium, phosphate, sulfur, sulfur containing compounds, nitrogen containing compounds, microbial metabolites, and microbes. The system includes a signal processor which is in communication with the sensor unit and which operates to provide a processed signal indicative of one or more dental conditions. The signal processor transmits the processed signal to a storage and display device (60 and 62) which displays a user detectable diagnostic message indicative of a dental condition, or suggestive of a remedial action. |
