ABSTRACT: The aim of this study was to evaluate the Vickers Hardness of four different denture base materials. Four different denture base materials were used in this study: Heat-cured pink acrylic resin, self-cured acrylic resin, heat-cured clear acrylic resin and polyamide denture base materials. To-tally 80 disc shaped samples which 2 mm thickness and 40 mm diameter were prepared. The samples were stored in distilled water after polished. Then, Vickers Hardness test was performed with TMTeck HV-1000B (200 gram at 15 second). The statistically analysis of obtained data was performed with use one-way analysis of variance test. The results showed that the highest Vickers Hardness value (18.57 HV) was identified in heat-cured (pink) acrylic resin, the lowest Vickers Hardness value (9.62 HV) was identified in polyamide denture base materials. The result of one-way analysis of variance test showed that there were statistically very highly significant differences between four denture base materials of Vickers Hardness (p
