Abstract
The present -concept of dentin adhesion depends on hybrid layer and sin tag formation. This concept is based on the removal of the smear layer [d the mineral phase from the dentin to open the dentinal tubules and create [ough intertubular microporosity allowing monomer infiltration into the posed collagen, thereby providing micro-mechanical retention.
The durability of resin-dentin bonds depends on the efficiency of resin filtration into these spaces and how well the resin is polyrnerized. Several tempts have been made to achieve this, including active application, creased application times and application of a separate hydrophobic resin ating.
The purpose of this study was to evaluate the ultramorphological pearance of the resin-dentin interface by scanning electron microscope in sociation with a simple light microscopic observation as well as evaluating c clinical performance of Xeno III and AdheSE systems applied by 3 rio ye methods.
Regarding the clinical assessment, 80 Class V composite restorations re placed in maxillary anterior teeth. The teeth to be restored were divided .o 2 groups; 1 for Xeno III and 2 for AdheSE, of 40 teeth each. Ten teeth re allocated for each adhesive application technique.
So, M1 and M2 represented teeth in which the Xeno III and AdheSE re applied using microsponges. R1 and R2 were those treated by rotary shes. Sonophoresis was used to apply the Xeno III and AdheSE in S1 and
teeth. Whereas, I and ‘2 were the ones allocated for iontophoresis.
