Abstract
The aim of this study is to evaluate the effect of incorporating sodium trimetaphosphate nanoparticles (TMPnano) and phosphorylated chitosan (Qui-Ph) in resin-modified glass ionomer cement (RIMC) used for cementation of orthodontic brackets, on the physical-mechanical and antimicrobial properties. Specimens of each material will be made: 1) CIVMR without TMPnano/Qui-Ph (Positive Control-F…
