Fig. 4. Dependence of (A) hardness and (B) elasticity (E) modulus on indentation
depth in the intact waxy surface containing both wax layers (filled triangles)
and the surface treated with dental wax and bearing the lower layer only (open
triangles). (C) The effect of contamination of the diamond tip. The curves in
A and B represent mean values of 200 indentation tests performed on each
sample type.
