This study aimed to compare the tensilestrength of heat cured acrylic resin and visible light cured acrylic resin.Materials and Methods: Twenty samples of acrylic denture base materials were prepared, ten samples of heat curedacrylic denture base materials and ten samples of visible light cured acrylic denture base material. After curing ofboth groups, the materials were subjected to tensile strength test with the use of Instron universal testing machine.Results: The results of the present study showed a high significant difference comparing between the two groups;heat cured acrylic denture base material showed a high significant tensile strength than the visible light cured acrylicdenture base material.Conclusion: heat cured acrylic denture base resin showed superiority in the tensile strength values than the visiblelight cured acrylic denture base material
