Abstract

This study compared porosity of denture resin cured by microwave energy to denture resin cured by the conventional heat method. Seven groups of 10 samples each were tested. The control samples of methyl methacrylate monomer were cured in a curing tank at 165° F for 9 hours. Four of the six experimental groups, consisting of samples made from Micro Liquid monomer (H.D. Justi Co., Oxnard, Calif.), were cured by microwave energy at varying wattages and times. The other two experimental groups contained samples of methyl methacrylate monomer cured by microwave energy. No significant differences were found in mean porosity between the control group and the four groups of microwave-processed samples that used Micro Liquid monomer. The two groups of microwave-processed samples of methyl methacrylate monomer showed a significantly higher mean porosity.
