Anas B, K. Kamalakanth Shenoy, Abdul Rashid, Anoop Mayya, Bhuma Jayaram

Purpose: To evaluate the tensile bond strength of silicone-based resilient liners attached to heat cured denture base material, when treated with different denture cleansing solutions.  Materials and Methods: Sixty cylindrical liner specimens (30 UFi GEL P™ and 30 GC RELINE™ SOFT) were tested for tensile bond strength after immersing in various denture cleansers for a period of six months. Instron Universal testing machine was used for testing the tensile bond strength. One way ANOVA and Mann- Whitney U tests were used for statistical analysis. Results: Tensile bond strength value of water and Fittydent increased over a period of six months, while Clinsodent showed a significant decrease in the Tensile bond strength value of UFi GEL P™.(p<0.05). Conclusion: In the present study UFi GEL PTM was observed as a better material when comparing with GC RELINETM SOFT with different variations in tensile bond strength when stored in denture cleanser over a period of 180 days.
Key words: Denture cleansers, tensile strength, silicone resilient liner.
