This paper reports the application of light-cured resin to cover the discoloration of the anterior teeth, focusing on the clinical efficacy of the two methods compared. The results show that the indirect method is better than the direct coating resin method in producing light-cured resin tooth surface. The former can improve the bonding effect and reduce the re-staining of tooth surface.
