Effect of Ageing on the Bond Strength of a Permanent Denture Soft Lining Material by M. Al‐Athel; R. Jagger; D. Jagger is a Dentistry article available to read on EtoBox.
**summary** Molloplast‐B is a widely used, long‐term, heat‐cured silicone denture soft lining material. Adhesion failure of this material to poly (methyl methacrylate) denture base material is a problem that is encountered clinically. The purpose of this study was to investigate the effects of long‐term immersion in water at 37 ± 1 °C and of accelerated ageing in water at 50 ± 1 °C on the tensile and shear bond strength values of this denture resilient lining material bonded to a heat‐cured denture base material. Immersion in water for 1 week at 37 ± 1 °C had no significant effect on the measured bond strength values. Longer immersion of specimens in water at 37 ± 1 °C led to a significant reduction in the measured tensile and shear bond strengths. The present study has demonstrated that the reduction in Molloplast‐B bond strength that occurs as a result of long‐term ageing in water at 37 ± 1 °C can be achieved in a shorter period of time by ageing the specimens in water at a higher temperature.
