N2  - Objectives: The aim of this study was to evaluate the effect of different postpolymerization methods on the residual monomer content of the heat cure dacrylic resins. Material and Methods: In this study QC20 heat cure dacrylic resin and SR-Ivocap high impact heat cure dacrylic resin were used. Each of acrylic resin material divided into three groups. Group I specimens were left untreated (GI- control). Specimens of group II (GII) were given postpolymerization treatment by microwave irradiation at 550 W for 5 minute. In group III (GIII), specimens were submitted to immersion in water at 55 ºC for 1 hour. Disc-shaped specimens of eachmaterial (n=10), with dimensions of 50 diameter and 3 mm in thickness were produced. The residual methylmethacrylate content of the test specimens was determined by ultraviolet spectrophotometry. In this study, the data on residual monomer were analyzed by applying ANOVA. If necessary, the differences between groups were controlled using DUNCAN multiple test. Results: The result of ANOVA indicated that there was a statistically significant interaction between acrylic resins and the applied processes in terms of residual monomer (p<0.05). Therefore, the main effect of the acrylic resins, and the applied processes were compared with each other separately. The lowest amount of residual monomer was observed in the group consisting of QC-20 samples. There were nosignificiant differences between QC-20 acrylic resin groups. There was statistically significant different for SR-Ivocap high impact acrylic resin samples which treated with microwave post-polimerization. Although the microwave polymerization didn’t reduce the amount of residual monomer of SR-Ivocap high impact acrylic resin samples. Conclusion: The effectiveness of the water bath (55 ºC for 1 hour) and microwave (550 W for 5 minute) post-polymerization treatments weren’t shown on the reduce the amount of residual monomer of QC-20 heat cured acrylic resin and SR-Ivocap high impact acrylic resin
