Purpose: To evaluate and compare the effect on water sorption and solubility of acrylic-based and silicone-based soft denture lining materials stored over a period of 7, 14, and 28 days in three different storage mediums [distilled water (AW), artificial saliva (AS), and denture cleaner (AC)].
Materials and methods: A total of 66 disk-shaped samples were fabricated and divided into two groups depending on the soft-liner used—acrylic (A; n = 33) and silicone (S; n = 33). The samples were subdivided further depending on the solution immersed—AW [synthetic water (SW); n = 11 each]; AS [simulated saliva (SS); n = 11 each]; and AC [solution for cleaning (SC); n = 11]. The samples were dried and weighed to measure the initial weight of the disks. All the samples were stored in their respective solution jars. On days 7, 14, and 28, the samples were reweighed to measure the weight after sorption. Water solubility and water sorption were calculated for the groups. The data collected was statistically analyzed by one-way analysis of variance (ANOVA) test and independent samples t-test.
Results: There is a significant difference in group A sorption and solubility values between the subgroups at days 7 and 28, having the highest sorption value for AC (0.7393 mg/cm2), followed by AW (0.659 mg/cm2) and then AS (0.6439 mg/cm2). The highest solubility was seen in the AS (0.525 mg/cm2) and the least in the AW (0.460 mg/cm2). In group S, sorption was seen highest in AW (1.1027 mg/cm2) and the highest water solubility was seen in the AW group (0.5055 mg/cm2) and least in the denture cleanser group (0.4850 mg/cm2). The mean water sorption values of the acrylic resilient liner were significantly greater (p < 0.001) than silicone-based liners in at 7–28-day time period. There was a continuous rise in water sorption up to day 14, and later it rose marginally.
Conclusion: The silicone soft liners have a lesser sorption and solubility rate than the acrylic-based soft liners. In comparison to soft liners made of acrylic and the silicone soft liners may provide better clinical success.
