From: A novel self-assembled oligopeptide amphiphile for biomimetic mineralization of enamel
Vicker’s hardness of the enamel specimens. A - untreated enamel, B - demineralized enamel by acid-etching, C - enamel coated with hydroxyapatite precipitates without the oligopeptide, D - enamel coated with hydroxyapatite precipitates in the presence of the oligopeptide. * p < 0.05. The right pane is the typical load–displacement curve of different samples under the Vicker’s microhardness test.
