| Abstract | |
The aim of this study was to evaluate by scanning electron microscope (SEM) photomicrographs the influence of application of halogen light-curing for fastening the set reaction of high-viscosity glass ionomer cements (GIC) by assessing the material/dentin interface. Twelve human primary canines were assigned in four groups (n=3) according to the GIC (Fuji IX, GC or Maxxion R, FGM) and application of halogen light-curing (60 sec or control-no external energy). Blocks with approximately 6 mm of height were buildup on previously pre-treated dentin surface in according to the experimental group. After storage at 37 degrees C, 100% humidity for 48 h, the specimens were then sectioned in slices with 1-mm thick. The slices were qualitative analyzed using SEM to evaluate possible structural changes. Two examiners independently evaluated the images in order to observe the spherical hollow spaces of each tooth. The photomicrographs revealed the presence of spherical hollow spaces in all experimental groups. However, in both groups that received halogen light-curing application, it was possible to observe that the presence of these hollow spaces decreased in size and quantity. It can be concluded that the halogen light-curing application positively decreases in size and quantity in the presence of spherical hollow spaces in GIC. (AU) | |
