Figure 4

Standard image and QLF image of a representative sample in the negative control group (no treatment, sample #09) at different investigation times. The dashed line indicates the ground surface where the QLF measurements were performed. (a) Prior to demineralisation. (b) Corresponding QLF-image: ΔF = 0.0%; ΔFmax = 0.0%. (c) After demineralisation (T-demin). (d) Corresponding QLF-image (T-demin): ΔF = − 10.4%; ΔFmax = − 33.7%. (e) 28 days after demineralisation (T28). (f) Corresponding QLF-image (T28): ΔF = − 12.6%; ΔFmax = − 33.5%.
