The purpose of this study is to evaluate and compare the hardness of silicone-based resilient liners attached to heat cured denture base material, when treated with different denture cleansing solutions. Sixty cylindrical liner specimens (30 UFi GEL P™ and 30 GC RELINE™ SOFT) were tested for hardness after immersing in various denture cleansers (water, Fittydent, Clinsodent) for a period of 180 days. Shore a Durometer was used for testing hardness. Mann- Whitney test, one way ANOVA tests were used for statistical analysis. Hardness value of water and Fittydent decreased the hardness value of UFi GEL PTM over a period of 180 days, while Clinsodent showed a high significant increase in the hardness value of UFi GEL PTM. When compared further, for 1st day and 180 days of hardness values in sub group, we found significant difference in the value of clinsodent (p=.042). Conclusion: In conclusion, UFi GEL PTM was observed as a better material when comparing with GC RELINETM SOFT with slight different variations in hardness when stored in denture cleanser over a period of 180 days. In addition, there is no much significant variation of mechanical properties of soft liners when stored in cleansing solutions and water. Hence, it is preferable to use denture cleansers due to its antimicrobial properties.
