Objectives : The objective of this study was to evaluate the influence of caries detection dye on the in-vitro tensile bond strength of adhesive materials to sound and carious affected dentin. Materials and Methods : Forty healthy and carious human molars were ground to expose superficial sound dentin and carious affected dentin. Caries Detector dye was applied to sound and carious affected dentin and rinsed. Subsequently the dentin was etched with 37% phosphoric acid and rinsed leaving a moist dentin surface. The adhesive (Single bond) was applied in single layers and light cured. A posterior composite (Filtek Z 250) were used to prepare the bond strength specimens with a 3 mm in diameter bonding area. Control and experimental groups were made with and without application of dye respectively. Each group includes both sound and carious affected dentin. After 24 hour immersion in distilled water, tensile bond strength (MPa) was measured using an Instron testing machine. Results : Analysis of variance (ANOVA) was used to evaluate the data. The tensile bond strength were significantly less in experimental subgroup than control subgroups. Conclusion : The tensile bond strengths were higher in sound and carious affected dentin without application of caries detection dyes.
