Viscoelastic properties of human dentin

Stress relaxation measurements were performed on thick-walled cylinders of radicular human dentin. The experimentally measured relaxation moduli were used to obtain an approximation to the logarithmic distribution function of relaxation times. This distribution function was used to predict the behavior of other viscoelastic properties. In particular, the prediction of the strain and strain rate dependence of the modulus was determined and compared with experimental results.
