Adhesion Mode Between Luting Cement and Canal Dentin
Objectives: This study examines the compositions of those adhesion modes between luting cements and canal dentin, and evaluated the dentin-cement-post interface by Laser-Raman spectroscopic. Methods: Three representative luting cements (zinc phosphate, glass ionomer and resin cements); two kinds of prefabricated posts (titanium and fiber-glass); six extracted intact human maxillary anterior teeth were used canal denting after endodontic treatment. Laser-Raman spectroscopy measure of cement, post and canal dentin before and after luting together. Results: There are no evident Raman spectra change cross the ZPC/dentin interface and glass ionomer/dentin interface, while cross the resin/dentin interface and resin/glass fiber post interface can be seen special Raman spectra. Conclusion: Laser Raman microspectroscopy is a useful analytical technique for evaluation interface between dentin and luting cements. Resin cement may interact with dentin and glass fiber post.
