dc.description.abstract           The objective of this study was to compare surface hardness, surface roughness and debris retention of dentoform tooth with alternative materials. Specimens were divided into five groups (n = 15/group): dentoform tooth, 50% wt. alumina filled epoxy resin (50%Al) , group3 = 60% wt. alumina filled epoxy resin (60%Al), 70% wt. alumina filled epoxy resin (70%Al)  and polymethyl methacrylate (PMMA). The vickers hardness was measured by using digital microhardness tester. Surface roughness of each cut surface was measured by using contact stylus tracing profilometer. Areas of debris retention on each cutting bur were investigated under stereomicroscope. One-way ANOVA revealed the highest vickers hardness (57.04 VHN) the lowest surface roughness value (3.98 µm) and  the lowest debris retention  (0.064 mm2) in dentoform group  when compared to other groups with a statistically significant difference (pen_US
