title: Effect of tinfoil substitute contamination on adhesion of resin denture tooth to its denture base.
abstract: At least one manufacturer claims that contamination of denture teeth with tinfoil substitute during processing is not detrimental. The purpose of this study was to determine whether tinfoil substitute contamination has any significant effect on the bond strength between acrylic resin denture teeth and their processed acrylic resin base. Eighty acrylic resin maxillary central incisors were processed to denture base material. The experimental group had the denture tooth ridgelap area contaminated with tinfoil substitute. The control group was not contaminated. The bond strength of the two groups was tested. The results indicate that contamination with tinfoil substitute significantly reduces the bond strength of acrylic resin denture teeth bonded to their denture base.
