Abstract

 Background: Elastic materials used in dental prosthetics to line removable dentures should be characterized by biocompatibility toward oral 
tissues, shape, and color stability; resistance to abrasion; and durability of the junction between the lining and the denture. The resilient lining 
materials present problems during clinical use, such as weakening of bond between lining and denture loss of resiliency, color alterations, 
and porosity. Materials and Methods: A study was conducted to determine the effect of disinfection on tensile strength of two commercially 
available soft liners. Sixty samples were divided into two groups and acrylic blocks were bonded with Viscogel and Molloplast soft liners. 
Specimens were tested after 24 h. The tensile bond strength was evaluated by a universal testing machine. Results: Results show that 
Molloplast-B has higher tensile bond strength than Viscogel after disinfection treatment. Conclusion: After the single disinfectant cycle, the 
bond strength values of both the soft denture liner materials were reduced but statistically, it was not significant
