| Summary: | AIMS: to evaluate the effect of microwave post-treatment in the reduction of residual monomer of different types of acrylic resin and evaluate the effect of microwave treatment time. MAERIALS AND MEHODS: three different types of acrylic resin materials are used; heat cured, light cured, and orthocryl. Specimens are subjected to additional curing with microwave and compared their residual monomer with the control group. ANOVA followed by Duncan multiple range test were used to determine the significant difference at P<0.05 level. RESULS: there was a significant difference (p<0.0001) in the amount of residual monomer released from the three tested materials. No statistical difference were seen between 5 and 10 minute microwave treatment for the heat cured and orthocryl acrylic resin but there is significant difference between 5 and 10 minute treatment for the light cured acrylic resin. CONCLUSIONS: There are different levels of residual monomer when comparing the tested materials with each other. Additional treatment with microwave after curing decrease the residual monomer of all the tested acrylic resin materials. |
