[Cariogenic potential of in-between-meals--results of oral plaque-pH-telemetry].

Using oral plaque-pH-telemetry the cariogenic potential of a sucrose-solution (10%), a sorbitol-solution (10%), of a roll with honey, a roll with jam together with sweetened coffee and the "Milchschnitte" has been examined. All sugar containing products cause a deep pH-drop in dental plaque. The duration of demineralization (time of plaque-pH below 5.5)-amounts to 75 min. after mouthrinsing with sucrose-solution, 80 min. after consuming a half roll with honey, 140 min. after eating a roll with jam and drinking sweetened coffee and 82 min. after consuming a "Milchschnitte". All these products shouldn't be used as in-between-meals or snacks without a consequent oral hygiene afterwards.
