| Research Abstract |
With a newly developed simultaneous measuring system for load and thickness, the relationships between properties of the oral mucosa and the pressure-pain threshold were evaluated. Thickness was significantly correlated with only amount of subsidence. Elasticity was significantly correlated with pressure, compressibility and amount of subsidence. However, no significant correlations were apparent between thickness and elasticity. Thickness of oral mucosa was correlated with amount of subsistence among the parameters associated with the pressure-pain threshold. Therefore, evaluating elasticity of the oral mucosa is important in predicting the generation of pain.
