Degradation in the complex modulus of dentin resulting from exposure to lactic acid. The complex modulus distribution is plotted as a function of distance across the modulus map. For the pH=5 condition, the bottom surface (at x=0) represents the surface exposed to lactic acid. The control condition represents the complex modulus for a map taken from the center of the specimen (not subjected to acid) and is plotted in terms of the average (line) and std dev. (green) of the complex modulus.
