چکیده انگلیسی
This study evaluated the thermal and morphological filler characteristics of self-adhesive resin cements. The cements (Embrace WetBond, MaxCem Elite, Bifix SE, G-Cem, and RelyX U200) were manipulated according to the manufacturers׳ instructions. Thermogravimetric analysis and differential thermal analysis were performed to obtain the glass transition temperature (Tg) and weight loss. Specimens were also obtained to characterize the zeta potential, the mean particle size and distribution, and the polydispersity by dynamic light scattering. An elemental analysis of the fillers was also conducted using X-ray spectroscopy analysis and micromorphology under SEM. MaxCem Elite contained the least organic matrix, followed by G-Cem, Bifix SE, RelyX U200, and Embrace WetBond. Bifix SE presented the highest Tg and G-Cem the lowest. Bifix SE presented the broadest filler size distribution, exhibiting lower zeta potentials and mobility. G-Cem was found to be a highly filler loaded cement with the lowest effective diameter, highest zeta potential and mobility. RelyX U200 presented chromium in the composition and G-Cem presented fluorine. Differences in the nature and chemistry of inorganic fractions seemed to dictate the morphology of the filler content and also the thermal behavior of the materials tested and, may consequently influence the clinical performance of self-adhesive resin cements.
