Abstract:

Acrylic resin is a material that is oft en used as a denture base. Acrylic resin is containing ethylene vinyl derived groups in the formula. Clinicians tend to select the acrylic resin as a denture base material because it has a non-toxic nature, not irritating, not soluble in oral fl uids, good aesthetics, easily manipulated, easy reparation and small dimensions change. Nevertheless, acrylic resin has the disadvantage that the content of methacrylate monomers inside the molecule produces unpleasant smell during the process of manipulation. Th is study aims to determine the eff ect of the concentration of mint leaf extract (Mentha piperita) added to the acrylic resin before polymerization to the hardness of acrylic plate. A total of 15 samples in this research in the form of plates which size 64X10X3, 3 mm that were divided into three diff erent groups: Group-1: Without the addition of mint leaf extract, Group-2: With the addition of mint leaf extract 0.25 ml and Group-3: With the addition of mint leaf extracts 0.5 ml. Th en the whole sample was left for a process of perfect polymerization and then was preceded with testing of the hardness using the micro Vickers hardness using 10 gf mass loads. Th e results of comparative parametric statistical tests one way ANOVA revealed that there was an eff ect of the addition of mint leaf extract (p<0.05), there is a signifi cant diff erence in hardness values between groups. Th en from the LSD (least signifi cant diff erent) revealed that there is any signifi cant diff erence in the value of acrylic resin hardness between each group in this study. So the addition of mint leaf extracts (Mentha piperita) aff ect the hardness of chemical activated acrylic resin.
