Development of a recording system for saliva pH with and complete denture by telemetry.
A new system for measuring saliva pH by radio telemetry was developed. The system was built into a lower complete denture and could operate for about 19 h. The maximum error in the range pH 5-8 was 0.15 pH, and the correlation when values were compared with those from a glass-electrode pH meter was 0.99. That this system operates successfully was confirmed in a clinical experiment.
