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). |
