Abstract

Purpose: To evaluate if three dentin treatments improved mechanical properties of demineralized dentin. Methods: Dentin slices were demineralized and treated with a universal adhesive, Scotchbond Universal (SBU), a cross- linker, Riboflavin (RF), and a calcium phosphate-based product, Teethmate (TM). The groups (n= 8 per group) were: Group 1: SBU, Group 2: RF + SBU, Group 3: RF + TM + SBU. Tensile tests were performed; stress/strain curves and E modulus were calculated. Differences between groups were assessed by one-way ANOVA and Duncan post hoc test. Results: At high strains, no significant differences in E moduli were observed between dentin specimens treated only with SBU and those treated with RF + SBU. A significantly higher E modulus was observed in dentin specimens treated with RF + TM + SBU. In the presence of an adhesive system, crossl inking collagen with RF and TM addition significantly improved mechanical properties of dentin.
