SEM-EDS and FTIR Analysis of Innovative Nanozirconia and Nanodiamond Filled Novel Resin Cement

Success of indirect restorations highly depends on the adhesive cement used. In the last couple of decades resin cement has evolved greatly and is preferred over other cements. It is important to understand the chemical composition and their interaction with teeth and the restoration in order to improvise and overcome the disadvantages. Here three groups were prepared, RelyX U200 dual-cure resin cement as control group or group 1and 10 vol% nanozirconia and 10 vol% nanodiamond modified cement as group 2 and group 3, respectively. 3-(Trimethoxysilyl) propyl methacrylate was the coupling agent used. Na-noparticles were added to coupling agent and mixed well on a glass slab, this was then mixed with the base of the commercial resin cement to obtain a homogenous mixture. Upon setting, the samples were crushed in mortar using pestle and made fine powder and incubated at 37⁰C and 100% humidity for 24 hours followed by SEM-EDS (SEM-EDS, Quanta FEG 450 USM) analysis. For FTIR analysis the powder form was made into the KBr pellet in a 1:10 ratio using samples and potassium bromide. The pellet was further analysed for chemical composition.
