Carbonated beverages are inseparable partof contemporary nutrition,whose consumption starts from the earliest age, but more and more data sends a serious warningto their harmful effecton general health, especiallyconnection with the obesityepidemic. Many developed countries have adopted regulations on their additional taxation, such as on tobacco. Harmful effect on dental tissues is also certainly proven, as a result of double effect of sugar and lowpH. Therefore, the possibility of enamel protection is verypopular. Natural polyalcohol, xylitolhas been thoroughly examined for a long time as a factor that inhibits metabolismof cariogenic bacteria. Lately, there is also informationon its direct interference with the process of remineralisationof hydroxylapatitelattice. The aim of the study was to examine the extent to which xylitol preventssurface damage of the enamel caused by the direct effect ofacideogenic carbonated beverage.
The test was carried out using SEM. The extracted teeth were kept for 24 hours in10% xylitol solution (experimental group), and in solution of artificial salvia(control group). Then, both groups were kept in Coca Cola solution at37 °Cfor12 hours and then returned to the original solution for 12h. Samples where then prepared for the analysis.
The analysis showed significantly smaller areas of direct destruction of crystal latticewhen treated with xylitol, which suggests the stimulation of remineralisation process. New zones of crystal accumulation have been observed.
The conducted research indicates possible protective role of xylitol when consuming carbonated beverages, which requires additional clinical and structural research.
