PURPOSE The purpose of this in vitro study was to investigate and compare the microleakage-occurring after the placement of a light-curing sealant-to unground permanent enamel which had been previously conditioned using 3 different application protocols. METHODS Sixty-three molars were randomly distributed in 3 different groups according to the application protocol of the sealant: (1) conditi...

In this research, gibbsite (GB) samples calcined at 200-1000°C (GB200-GB1000) were produced. These GBs were used to adsorb orthophosphoric, pyrophosphoric, and tripolyphosphoric acids from aqueous solutions. The properties (amounts of hydroxyl groups, specific surface areas, mean pore diameters, and solution pHs) of the GBs were investigated, and their adsorption capacities for phosphoric acids...

BACKGROUND The aim of this research is to evaluate cyclic (CSBS) and static shear bond strengths (SSBS) of metal orthodontic brackets bonded to composite laminates using different conditioning protocols. METHODS A total of 80 direct nanofilled composite laminate veneers were prepared on permanent incisors and divided into four equal groups according to different surface treatments. In group 1...

The aerospace industry mostly uses the aluminum alloys 2xxx and 7xxx series for their fuselage construction, some of them are assembled using structural bonding because it is strong, easy during fabrication process, resistant to corrosion, non-toxic. anodization process a proven surface treatment method bonding. Phosphoric Sulfuric Acid Anodizing (PSA) an eco-friendly alternative as chromate-fr...
