Mechanical strength of human oral cells was investigated with two kinds of tests. Oral mucosa keratinocytes were picked from minor oral surgeries or dental extractions and cultured. The cells separated each other were dispersed in culture media in volume fraction of about 0.4. In a flow test, the test fluid was sheared with a cone-plate type rheometer under shear stress of 1-5 Pa. We estimated survival ratio of the cells after the test. But there were almost no influence of the shear on the ratio. On the other hand, we have conducted direct compression test to the single cells. Collapsed cells were observed when the gap size became smaller than the diameter of the cells.
