Bond strength and candidal growth inhibition of the VLC soft liners in comparison to silicone and acrylic soft liners

ABSTRACT

The purpose of the present work was to compare bonding of the visible light-curved VLC soft liners to denture base resin with that of silicone and acrylic soft liners to denture base resin. Another purpose to study the effect of the studied soft lining materials on Candida albicans growth. Specimens were prepared from denture base resin bonded to the different denture soft liners. An Instron universal testing machine was used to measure the tensile failure of the different specimens. Other specimens from the different materials were prepared and were cultured with isolated Candida albicans. The percentage of growth inhibition of Candida albicans was compared. The results showed that the heat-cured silicone soft liner had the highest bonding values to denture base resin, followed by the two tested VLC soft liners. It was also shown that the self-cured acrylic soft liner had the highest inhibition values of Candida albicans growth while the silicone material had the lowest inhibition values of Candida albicans growth
