Abstract
The possible interaction between dentin and a proprietary dentin bonding agent (DBA), Gluma, was studied by Phase Photoacoustic FTIR. The determination of the existence and nature of a chemical bond between the DBA and the substrate can be of great importance in explaining the performance of these agents. Human dentin was treated by solutions of 2-hydroxyethyl methacrylate (HEMA), glutaraldehyde and a combination of both (Gluma Primer). Spectra of dentin samples treated with 35% and 100% HEMA as well as Gluma Primer show loss of both the hydroxyl (O-H stretch) and methylene (CH2 stretches) peaks from HEMA while other peaks are retained, even after thorough washing. This indicates a reaction between HEMA and the collagenous fraction of dentin.Keywords
