Figure 1. Representative light micrographs of cement/dentin interfaces stained with Masson’s trichrome: mineralized dentin (green), resin cement (clear with filler particles), exposed protein (red). (A) A distinct red zone of exposed protein was identified in the sections recovered from specimens etched with phosphoric acid (Calibra). (B,C) A slight purple line representing collagen partially reacted with resin cement is detectable at the interface between dentin and the self-etching primer (B; Panavia F 2.0) or Multilink Sprint (C) (arrows). (D-F) No signs of demineralization and/or exposed protein (red stain) are detectable at the cement/dentin interface of Rely X Unicem (D), G-Cem (E), and Bis-Cem (F). Original magnification, 100x; bar = 10 µm.
