paper. Each adhesive was applied to prepared surfaces. Each silicone denture relining material (SiDRM) was mixed and injected into sample mold (an internal diameter of 10mm and a thickness of 3mm) on the surface of polished denture base material to cover the bonding area. Immediately after making test sample, specimens were stored in water (35 ◦C) for 5min to cure SiDRM. Equal amounts of RM A and B were mixed and applied to cover surface of RS and margin (a thickness of 50 m) for RM applied group. All samples were kept for 10min after removing fromwater (35 ◦C) at room temperature (23 ◦C). After keeping at room temperature, specimens were stored in water (37 ◦C) for 30min. Bonding Strength (BS) was evaluated using a universal testing machine (SHIMAZU EZ-L) at 10mm/min cross-head speed. The data were statistically analyzed by one-way ANOVA, Turkey-Kramer test and T-test (p<0.05, n=7). Results: The results (Table 1) demonstrated that significant differences within RELINE II systems and between RELINE II systems and other materials were observed. Conclusion: This study indicated that RELINE II systems showed higher BS compared to other materials. In addition, it is possible to achieve better adhesiveness by using RM.
