Design outcomes

Primary

Measure	Time frame
Surface chemical charactristics of teeth. Timepoint: The characteristics will be measured only once in each intervention and control group after the extraction of the teeth and their mounts, thus it will be done at least 4 weeks after the start of the study. Method of measurement: Raman test.;Microhardness of teeth. Timepoint: The characteristics will be measured only once in each intervention and control group after the extraction of the teeth and their mounts, thus it will be done at least 4 weeks after the start of the study.
