| Research Abstract |
The texture which shows physical properties, such as hardness of a food, was associated with the swallowing easy, and the difficulty of swallowing was shown as a hardness stress and coherence went up. However, in a small alteration of the texture, the muscles activity during swallowing was not affected. When the food texture became remarkably large during free swallowing of the edentulous, the muscles activity became large and strong tongue pressure produced it still longer. Moreover, when a texture was large, the muscles activity with artificial tooth arch tended to become quick greatly.
