Rinsing with Inula viscosa tea was performed in-situ.
Erosive attack was induced by incubation of enamel samples in HCl ex-vivo and calcium- and phosphate loss were determined photometrically.
Fluorescence microscopic approaches yielded a significant reduction of adherent bacteria and glucans after rinse with Inula viscosa tea.
Transmission electron microscopy indicated a modification of the pellicle’s ultrastructure but no enhanced protection against erosive noxae.
