| Summary: | Background and aim: Denture adhesives augment the retention and stability of the complete denture. The included studies have not directly compared tensile bond strength between zinc and zinc-free denture adhesives. This study compared the tensile bond strength of zinc-containing and zinc-free denture adhesives on different denture base resin materials at various intervals.Material and methods: Four groups of denture base resin materials (Acralyn H, Lucitone199- DB1, SR Ivocap-DB2, Polytray-DB3) were fabricated using different polymerization techniques. Each group had ten specimens. The control group consisted of resin cylinders coated with artificial saliva, while the test groups had denture adhesive applied between the test and control cylinders. Tensile bond strength was measured using a universal testing machine.Results: The tensile bond strength values of Fixodent with DBI &DB3 and DB2 &DB3 at 5 min (P < 0.01), 3 hours (P < 0.01), and 6 hours (P < 0.061 and P < 0.020) alongside with DB1 & DB2, DBI & DB3, and DB2 & DB3 at 12 hours (P < 0.01) were found to be statistically significant. The tensile bond strengths variations of Fittydent with DB1 & DB3 and DB2 & DB3 at 3 hours (P =0.013, P =0.012) and 6 hours (P < 0.01), and DB2 & DB3 at 12 hours (P=0.015), was statistically significant at 0.05 level.Conclusions: The zinc-containing and zinc-free denture adhesives exhibited a significant increase in tensile bond strength compared to the control group (artificial saliva) at all time intervals. |
