Part 2. Percentage measurement values for cylinder 1 (1 min etch), cylinder 2 (2 min etch), cylinder 3 (4 min etch) and cylinder 4 (8 min etch); by SRI (TableTop and OptiPen), SH (% scale on the y-axis to the left). Average enamel loss (μm) by WLI on enamel sample and WLI on impression are shown (downward scale from zero to increasing enamel loss expressed by negative eth depths) on the y-axis to the right). The dotted and dashed lines represent the trend lines for the registrations by SH, SRI and WLI, respectively
