INTRODUCTION: In partial and full dentures, soft lining materials are used to evenly distribute the forces on the prosthesis. Effective brushing for cleaning soft linings damages the surface and distrup its structure. For this, the use of denture cleaners is an effective method in preventing Candida colonization and denture stomatitis. The aim of our study is to investigate the effects of denture cleaners on the tensile bond strength between silicone-based soft lining material and acrylic resin base. MATERIAL AND METHOD: In our research, 60 specimens were fabricated in dimensions of 10x10x40 mm using heat cured poly-methyl methacrylate denture base resin (Meliodent Heat Cure). All specimens were subjected to 10,000 thermal cycles of 5 to 55°C simulating 1 year of clinical use. Silicone-based soft lining material of 3 mm thickness was applied between two acrylic resins (Ufi Gel P). According to the cleaning material used (1% NaOCl, Corega, distilled water), 3 groups were randomly formed (n=10). The samples were stored in 1% NaOCl solution for 10 minutes and in Corega solution for 3 minutes. 180 day denture cleaning was clinically simulated. All specimens were placed under tension until failure in a universal testing machine at a crosshead speed of 5 mm/minute. RESULTS: A statistically significant difference was found between denture cleaners in terms of tensile bond strength. As a result of the Tukey HSD Test conducted to determine between which cleaner groups the significance is; The tensile joint strength of the Corega group was found to be significantly lower. There was no significant difference between Distilled Water and Sodium Hypochlorite groups. CONCLUSION: The tensile bond strength values of all our samples, the clinically acceptable bond strength between the soft linings and the acrylic denture base were found to be higher than 0.44 MPa and its use is recommended with confidence.
