In this work, the influence of organic and water content in dental enamel on its mechanical properties was investigated. The effectiveness of the deproteinization treatments (heating and chemical treatment) were assessed by determining the organic content in enamel. Chemical treatment proved more suited for protein removal, as - contrary to heating - it does not alter enamel’s ultrastructure. Structural characterization revealed the interfaces in enamel having multiple mineral-to-mineral contacts, meaning that a protein layer, enveloping enamel’s crystallites, is absent. The protein content had virtually no effect on elastic modulus, hardness and creep behavior, as assessed by nanoindentation. However, a higher water content resulted in a lower elastic modulus and increased creep and recovery in the enamel.
