Healthy volunteers are observationally wearing an intraoral device with bovine tooth samples
once for two hours. Afterwards, Calcium release from the bovine enamel and dentin samples is
measured after extraoral erosion.
Total protein concentration within the formed salivary pellicles on the bovine samples is
determined. Further Salivary parameters (unstimulated and stimulated saliva flow rate, pH,
buffer capacity, albumin and total protein content as well as concentration of inorganic
calcium, phosphate and fluoride) are being measured.
The aim of this study is to investigate whether gender differences in the salivary
composition correlate with predisposition to erosion.
