The objective of this study was to synthesize and assess unfilled and filled (silica nanoparticles) dentin adhesive polymer. Methods encompassing SEM (SEM)-namely, energy dispersive X-ray spectroscopy (EDX), micro-tensile bond strength (μTBS) test, Fourier transform IR (FTIR), and micro-Raman spectroscopy-were utilized to investigate Si particles’ shape and incorporation, dentin bond toughness, degree of conversion (DC), and adhesive-dentin interaction. The Si particles were incorporated in the exptl. adhesive (EA) at 0, 5, 10, and 15 weight% to yield Si-EA-0% (neg. control group), Si-EA-5%, Si-EA-10%, and Si-EA-15% groups, resp. Teeth were set to form bonded samples using adhesives in four groups for μTBS testing, with and without aging. Si particles were spherical shaped and resin tags having standard penetrations were detected on SEM micrographs. The EDX anal. confirmed the occurrence of Si in the adhesive groups (maximum in the Si-EA-15% group). Micro-Raman spectroscopy revealed the presence of characteristic peaks at 638, 802, and 1300 cm-1 for the Si particles. The μTBS test revealed the highest mean values for Si-EA-15% followed by Si-EA-10%. The greatest DC was appreciated for the control group trailed by the Si-EA-5% group. The addition of Si particles of 15 and 10 weight% in dentin adhesive showed improved bond strength. The addition of 15 weight% resulted in a bond strength that was superior to all other groups. The Si-EA-15% group demonstrated acceptable DC, suitable dentin interaction, and resin tag formation.
