A numerical analysis for tooth is required to estimate a stress on biting, become the dentist sometimes find an accident which a cracks in tooth break out. As the tooth consists of anisotropic material, it shows the anisotropic behaviors. The purpose of this study is to suggest a method to identify the anisotropic properties by the micro-indentation method. Micro-indentation method has been applied only the isotropic material. In order to expand to anisotropic materials, a formulation has been introduced. The mechanical properties of a tooth can obtain by the proposed method and GA. In addition, CT-value for a tooth has been measured by X-ray CT. CT-value will depend on the density, and the modulus of elasticity will depend on the density. In this paper, it is demonstrated that the modulus of elasticity of tooth can be measured by X-ray CT.
