| Research Abstract |
The present study has realized the effective use of electron beams in order to reduce residual monomers, for the purpose of providing safe dentures to senior citizens. The low-energy electron beam irradiation system was newly designed for dentures. This has enabled the denture surface with complicated profiles to be irradiated. The quantity of eluted MMA monomer decreased under irradiation. It was shown that E. coli cells on PMMA resin plate died when subjected to electron beam irradiation.
