[Sugar-free, tooth-protecting chewing gum and candy. Results of a 7-year study].


Experiences of 7 years with sugarless chewing gums and lozenges (tab. I and II) regarding their tooth protective properties are reported. Telemetry of interproximal plaque pH allows to assess acid formation from carbohydrates by plaque bacteria under almost natural conditions. Altogether, 5 chewing gums and 8 lozenges containing sorbitol or mixtures of sorbitol and hydrogenated oligosaccharides were investigated. Lowest pH values during and after chewing sugarless gums varied between pH 6.0 and 7.3. When sucking sugarless lozenges the recorded pH values were between 5.8 and 7.0. In contrast to lozenges, the consumption of sugarless chewing gums becomes particularly important due to their greater stimulation of saliva and buffering capacity of oral fluid. All products tested did not acidify interproximal plaque below the critical pH and therefore comply with the regulations of the Swiss Federal Health Authorities with respect to the labeling or marketed sweets with "safe for teeth". New non-fermentable sugar-replacing substrates are being developed. Their utilization in foodstuffs and sweets is being discussed.
