PURPOSE: A major complication associated with the use of resilient denture liners (RDLs) is a change in @entity3358 over time. In vivo studies on the deterioration of RDLs over time are needed. We aimed to investigate the influence of @entity1 characteristics on the @entity3358 of acrylic-based RDLs (ARDLs) embedded in complete maxillary dentures. We hypothesized that 1 month after application of the ARDLs, the @entity3358 would be influenced by age, saliva condition, occlusal force, smoking, drinking, denture wearing during sleeping, denture cleanser usage, and denture type. METHODS: Thirty complete maxillary denture wearers were recruited after obtaining informed consent. One investigator measured the Shore D @entity3358 of the commercially available ARDLs, Soften (SFT), @entity10751 Soft (FDS), and Bio Liner (BIO) using a Vesmeter(  ). The salivary flow rates and pH values and the occlusal force were measured for all @entity1 before initiation of the study. T-tests and Pearson's correlation coefficients were used for the statistical analyses. A p-value of <0.05 was considered statistically significant. RESULTS: Smoking, wearing dentures while sleeping, use of denture cleansers, and denture type were associated with an increase in the @entity3358 of the RDLs. The resting saliva pH only influenced the @entity3358 of the SFT ARDLs. CONCLUSIONS: Smoking, denture wearing while sleeping, denture cleanser usage, denture type, and resting saliva pH are important predictors of the deterioration of ARDLs over time.
