The impact of flavoured mineral water drinks and sugar substitutes available on the Polish market on exogenic erosion of teeth enamel - in vitro study: preliminary results

An increase in the consumption of soft drinks has been observed in recent years. Flavoured mineral waters are often treated as an alternative to still mineral waters. The aim of our study was to determine the influence of sugar substitute solutions and flavoured mineral water drinks available in Poland on the enamel dissolution. The following parameters were determined: pH, titratable acidity and the concentration of phosphorus for flavoured mineral water. Solutions of xylitol, erythritol, stevia and glucose-fructose were tested to discover the impact of the sweeteners on exogenous erosion. Both flavoured mineral water and sweeteners tested in this study cause exogenous erosion of enamel according to the results of phosphorus released from hydroxyapatite. The erosive potential of the tested sugar substitutes concerned as beneficial for our health was similar to the glucose-fructose syrup.
