Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Our intention is to prepare Polymethylmetacrylate squers on orthodontical brackets,then prepare the surface of the sample and measure the surface roughness with a profilimeter and get the mean value in Ra units, then place the brackets on lower premolars and molars for 12 hours, remove them and examine the biofilm formed with confocal scanning microscope.
