Abstract

The deformation behavior of the dentin in intact human teeth is studied during diametral compression in air, water, and a 18% aqueous solution of NaCl. The deformation behavior of the dentin during diametral compression is shown to change from quasi-brittle during tests in air to viscoelastic during tests in water and the aqueous solution of NaCl. In all cases, a main crack in the dentin develops as in a viscoelastic material, i.e., via microcrack coalescence.

流体对径向压缩过程中人牙本质变形行为的影响

摘要

在空气，水和18％NaCl水溶液的径向压缩过程中，研究了完整牙齿中牙本质的变形行为。显示在径向压缩期间，牙本质的变形行为从在空气中测试期间的准脆性变为在水和NaCl水溶液中测试期间的粘弹性。在所有情况下，牙本质中的主裂纹都像粘弹性材料一样，即通过微裂纹聚结而发展。
