The purpose of this study was to measure the permeability of primary molar and permanent premolar dentin at various thicknesses from the pulp and to correlate permeability with the tubule density and diameter of dentin using SEM. The data were examined for statistically significant differences using two-way analysis of variance, multiple comparison Scheffe, and regression analysis. The permeabi...
Materials and method Silver nanoparticles have gained more attention owing to their broad spectrum of antibacterial activity and low cost of manufacturing. In the present study, starch coated silver nanoparticle were synthesized and characterized by SEM/ EDX and UV/Vis spectroscopy. Starch coated nanosilver was tested for their antibacterial activity against various microorganisms that are comm...
PURPOSE The aim of this study was to evaluate: 1) the effect of five dentin desensitizing agents (DDAs) on permeability using hydraulic conductance, and 2) morphological tubule changes with scanning electron microscopy (SEM). MATERIALS AND METHODS The agents tested were Seal & Protect, Gluma Desensitizer, HurriSeal, D/Sense 2, and Super Seal. Thirty extracted human molars were sectioned into ...
