Nanoindentation tests showing hardness (a) and modulus (b) for sound enamel, demineralized enamel, and samples treated in control (without peptides), P26 and P32 for 7 days in artificial saliva. The error bars represent standard deviation (n = 5 per group). Demin: demineralization (2 h). Student’s t-test was applied to identify differences in the hardness and elastic modulus between etched and repaired enamel (p ≤ 0.05).
