Abstract
Aim: This study aimed to determine the cytotoxicity of polymethylmethacrylate copolymers.Material and Methods: The polymethylmethacrylate resin was used to fabricate the samples. Ethyl-methacrylate, butylmethacrylateand isobutyl-methacrylate, were used to form the copolymerization of polymethylmethacrylate. 10%-20%-30%-40%ethyl-methacrylate, butyl-methacrylate and isobutyl-methacrylate monomers were added to the methyl-methacrylate, which is themonomer of the control group, and 13 different groups were formed. Five specimens (n=5) for cytotoxicity test were prepared foreach group. Cytotoxicity effects of the resins at 24th and 48th hours were evaluated by MTT assay. The data of the cytotoxicity testwas analyzed by applying one-way variance analysis.Results: The effect of monomer type and monomer percent on cell viability was significant in both periods (p< 0.01). The percentageof cell viability of all groups at both times was over 90%. The cell viability showed a tendency to decrease by increasing the percentageof monomer added in both periods. The highest and lowest cell viability in 24th hours were observed in 10% ethyl-methacrylate and30% butyl-methacrylate groups respectively, while the highest and lowest cell viability in a 48th hour was observed in 10% butylmethacrylateand 40% butyl-methacrylate groups, respectively.Conclusion: The cytotoxic effects of copolymer resins were not observed at 24th and 48th hours. Cell viability was found at more than90% in both periods. It was shown that the copolymer resins formed by the addition of 10%, 20%, 30%, and 40% by volume of isobutylmethacrylate,butyl-methacrylate, and ethyl-methacrylate to the methyl-methacrylate were biocompatible materials.
