本研究的目的是探讨牙本质小管的位置和方向对牙本质抗拉强度的影响。制作了12组不同位置、不同牙本质小管方向的哑铃形标本。拉伸试验是在37℃的蒸馏水中进行的，平行方向的抗拉强度明显大于垂直于方向的抗拉强度；根部牙本质的抗拉强度明显大于冠状牙本质的抗拉强度。然而，在根部牙本质中，与牙本质垂直的小管的抗张强度与抗拉力不同。这些结果表明，牙本质的抗拉强度因牙本质小管在牙齿中的位置和方向而不同。
The purpose of this study was to investigate the effects of the location and orientation of dentinal tubules in the tooth on tensile strengths of the dentin. Dumbbell-shaped specimens of 12 groups from various locations and dentinal tubule orientations were prepared. The tensile test was performed in distilled water at a temperature of 37 degrees C. The tensile strengths of the parallel to the orientation were significantly greater than those of the perpendicular to the orientation; the tensile strengths of the radicular dentin were significantly greater than those of the coronal dentin. Nevertheless, in the radicular dentin, the tensile strengths of the perpendicular to dentinal tubules differ with respect to tensile forces. These results suggest that tensile strength of the dentin varies according to the location and orientation of dentinal tubules in the tooth.
