Research Abstract |
Dentin that is a major component of tooth has the dentin tubules as its microstructure. The aim of this study was to evaluate the relationship between orientation of the dentin tubules and mechanical strength of the dentin. Orientation of the dentin tubules was analyzed using a scanning electro microscope and coefficient of elasticity and coefficient of viscosity were measured using a creep meter. The mechanical analysis showed that elasticity was larger in parallel than in perpendicular to the direction of the dentin tubules.
