Fig. 6 — (A) Raman map of dentin specimen fractured to provide cross-sectional view of the acid etched carbide bur-created smear layer/demineralized dentin/undisturbed dentin. Spectra acquired at 1-μm intervals beginning at the acid etched carbide bur-created smear layer, extending into the demineralized dentin and, finally, into the undisturbed dentin. (B) Raman map of the molecular structure of the acid etched diamond bur-created smear layer and subjacent demineralized/undisturbed dentin. Spectra acquired at 1-μm intervals beginning at the acid etched diamond bur-created smear layer and continuing into the undisturbed dentin (Spencer et al. [70] with permission of IADR/AADR).
