E xtrinsicdiscoloration in the anterior region of the tooth will affect the appearance. Ekstrakoronal bleaching is treatment of choice to repair teeth that have discoloration caused by contamination from exogenous soeces, such as smoking, drinking tea and coffee. There are 2 methods in bleaching, first is in office bleaching with 30% hydrogen peroxide and second is home bleaching with10% carbamide peroxide. Hydrogen and carbamid peroxide is an effective forbleaching agents, higher contcentrations are more effective, but there are reports on their surfase roughness effect on resin composites. Nowadays nanofill composite are recommended for restorations, nanofil has a small size and smooth 1-5 um) that have resistantce to abrasion and can reduce the surface roughness of resin composite. Surface roughness of composite resin can lead attach of debris that's dificult to remove, these condition will causes secondary caries and discoloration on nanofill composite.
