Abstract

objective: This study was conducted to assess the shear bond strength of orthodontic brackets bonded with total etch adhesive systems containing silver nanoparticles (AgNPs) and interfacial analysis using Environmental Scanning Electron Microscope (ESEM).   materials and methods: The AgNPs was synthesized and characterized by (UV-Vis) spectroscopy and Transmission Electron Microscope (TEM). Adper Single Bond 2 was used as the total etch (TE) adhesive. 48 teeth were divided into 40 teeth for shear bond strength test and 8 teeth for ultra- morphologic examination. For shear bond strength test 40 teeth were randomly divided into two equal groups according to the addition of silver nanoparticles, (TE) teeth were bonded with adhesive not containing silver nanoparticles and (TES) teeth were bonded with adhesive containing silver nanoparticles. Each group was subdivided into 2 subgroups: C1  (10 specimens): 24 hours aging period. C2 (10 specimens): 3months aging period. Finally two representative samples of each group were analyzed using an (ESEM) for interfacial analysis.   result: After 24 hours aging, there was non-significant difference between mean shear bond strength values of the adhesive contain silver nanoparticles (5.09± 1.69) and the nanoparticles free adhesive (4.69± 1.42). Also after 3 months aging there was non-significant difference between both adhesives with (6.31±1.12) and without (5.14± 1.16) addition of silver nanoparticles.   conclusions: The addition silver nanoparticles to total-etch adhesive systems did not hinder bonding of resin composite to enamel. Silver nanoparticles didn't antagonize penetration of resin tags into enamel. Bonding of brackets with resin composite using total etch adhesive system containing and non- containing Silver nanoparticles doesn't deteriorate with time.
