OBJECTIVE This study evaluated the cytotoxicity and genotoxicity of fixed orthodontic treatment with three different light-cured orthodontic bonding composites by analyzing micronucleus (MN) formation in the buccal mucosa during a 6-month period. METHODS Thirty healthy volunteers were selected from consecutive patients referred for orthodontic treatment. Equilibrium 2 brackets and molar tubes...

The effects of polypropylene fibres on mortar and cement-paste cracking were investigated using different amounts fibre fractions eccentric rings under restrained-shrinkage conditions. Eccentric-ring tests conducted to investigate early-age shrinkage cracks. characteristics restricted cementitious materials described by evaluating the time concrete mixtures that are less likely crack. Different...

This study investigated the mechanical properties and antibacterial of hexagonal boron nitride titanium dioxide (h-BN-TiO 2 ) nanocomposite modified traditional glass ionomer cement. The mechanism formation h-BN-TiO was elucidated by conducting molecular dynamics (MD) simulations using Material Studio (MS) software. Furthermore, synthesis original growth method nanosheets (h-BNNs) nanoparticles...
