This clinical report describes a simple technique capable of coloring a tooth surface with a composite adhesive system. The enamel surface to be colored was etched with phosphoric acid and a self-polymerizing bonding agent (Clearfil New Bond) was applied. A high-flow opaque composite (Metafil Flow Opaque) was painted with a brush and light-exposed. The surface shade was then adjusted to the adjacent teeth with a high-flow composite (Estelite LV high-flow). The treatment could be completed in a single appointment. After an observation period of six months, the restoration was functioning satisfactorily.
