Micro abrasion

The objective was to compare the colour improvement of white spot lesion and the colour stability of treated enamel to after discolouration in vitro. Method: Artificial WSLs (2*2 mm) were created on the outer surface of 60 permanent premolars and randomly allocated to 4 groups. Specimens were treated with infiltration (RI), CPP-ACP (CPP), and micro-abrasion (MA) or remained untreated (UT).

Functional electrochemical coatings: hydrophobic Ni-TiO2 , catalytic Ni-CeO2 -CuO, and cutting, abrasive Ni-CBN all need to be durable and corrosion resistant to ensure stability in usage process. The presence of chemically inert nano and micron particles in the composite coatings leads to surface texture change and corrosion resistance increase.

Wear of sliding surfaces can occur by one or more wear mechanisms, including adhesive, abrasive, fatigue, impact, corrosive, and fretting. The wear rate, a measure of wear, generally needs to be minimized (Bhushan, 1996). As the dimensions of components and loads used continue to decrease (such as in microelectromechanical systems or MEMS), scratching/wear and mechanical properties at the micro- to
