Gradual changes of oral tissues require that complete or partial denturesbe relined to improve their adaptation to the supporting tissue. This study aimed to evaluate the tensile bondstrength of heat cure acrylic and Valplast denture base materials to silicone self-cure soft lining material stored inartificial saliva.Materials and method: Two types of self cured silicone soft lining material (one with prime the other without prime oradhesive) applied to polymethylmethacrylate and injection-molded nylon denture base materials for tensile bondstrength testing using Instron machine.Results: The comparison between all test groups after (48) hours immersion in artificial saliva were highly significantly different fromeach other except for the comparison between groups PSP and VSP in which theirmeans were non-significant. After (12) weeks,the comparison between all test groupswere highly significantly different fromeach otherwhen compared statistically.Conclusion: This study indicated that prime (adhesive) increase the bond strength of the silicone soft lining materialswith denture base materials. Silicone soft lining materials are affected by artificial saliva storage
