[Intraoral pH measurement by determination of acidogenic potentials of dietary materials].
The intra-oral production of acid by plaque bacteria from sucrose, glucose and sorbitol and test products with sugar substitutes as well was estimated by pH-telemetry which permits the digital registering and collection of data. A pH-drop was not observed when sorbitol or xylitol were offered as a substrate to the dental plaque. The small differences of intensity and duration of the telemetric estimated acid production by dental plaque due to the test products (with sucrose or sorbitol/glucose) exhibited different cariogenic challenge in the animal experiment and in the intra-oral cariogenicity test, but with high probability they have not any practical significance for the preventive dietetic recommendations.
