Marginal Leakage of a Softened Temporary Restoration as Determined by Microorganism Penetration.

Abstract

The ability of Proteus vulgaris to penetrate through IRM and gutta percha was investigated by using an in vitro model system consisting of extracted teeth embedded in acrylic. Cavity preparations in the embedded teeth which were sealed with gutta percha allowed penetration within 48 hours of proteus in 100% of the models, whereas, those sealed with IRM allowed penetration in 36% in 48 hours. The model system was valuable in detecting the penetration of bacteria through temporary restorative materials. (Author)
