Figure 1. Light micrographs and Raman spectra of Single Bond adhesive/dentin interface (a) and Single Bond adhesive-infiltrated demineralized dentin (AIDD) without or with removal of ethanol before polymerization (b, c, respectively). These 3-µm sections were stained with Goldner’s trichrome; corresponding Raman spectra were recorded from the intertubular area of the samples.

Figure 2. Light micrograph (a) and corresponding Raman mapping spectra (b) acquired at 1-µm intervals across the Single Bond adhesive/dentin interface. The spectra marked with arrows (c) were recorded from sites corresponding to the demarcations noted on the light micrograph.

Figure 3. Raman intensity ratios of 1454/1667 (a) and 1113/1667 (b) and penetration of BisGMA monomer and BisGMA/HEMA (c) as a function of spatial position across the adhesive/dentin interface. The comparable relative ratios calculated from the AIDD represent the optimum hybrid and are presented for comparison.
