概要	Purpose : We investigated the change in hardness of ethylene-vinyl acetate(EVA) material by heat-molding Mouthguards(MGs). Methods : Five different EVA sheets were heat-molded on the model to produce MGs. The anterior and molar regions of MGs were cut out for sampling materials. Results : In most samples, their hardness rose after heat-molding, and the hardness level was higher in anterior regions than in molar regions. Conclusion : The hardness of EVA used in MG materials tended to increase after heat-molding.
