Abstract
Objective: Depending on the degree of saturation and time that pigments have been in the dental tissue, teeth with severe color change may have a poor prognosis for bleaching treatment.Case Report: In the reported case, after a careful clinical history and evaluation of clinical case a conservative treatment with composite resin restoration was carried out on superior central incisor with severe darkening. Direct composite resins with different opacity and translucency in association with resin pigments and a conservative technique were used guaranteeing a minimal intervention and giving a natural aspect to the tooth. The use of pigments made possible less wear of dental structure for insertion of the composite resin, mimetizing the restored tooth with the corresponding teeth.Conclusion: It was concluded that in some cases where indirect restorations would be indicated, when different kinds of dental materials and techniques are applied, direct restorative treatment would be a great option for esthetic restorations.

The smile harmony has become an important aspect to be considered in Esthetic Dentistry, especially with the development of adhesive systems for restoring dental structures
The direct composite resin systems are suited for stratifications, or layering of various opacities and colors of dental composites
The study of colors and dental structures combined with a correct choice of dental materials enables a proper interaction between the tooth structures and restorative materials
Summary
The smile harmony has become an important aspect to be considered in Esthetic Dentistry, especially with the development of adhesive systems for restoring dental structures. With the development of composite resin and adhesive techniques it is possible to make direct esthetic restorations, applying full knowledge of the dental materials science, and in some cases, without laboratory. The direct composite resin systems are suited for stratifications, or layering of various opacities and colors of dental composites These resources offer dentists the opportunity to reproduce details of natural teeth with better cosmetic results than many indirect esthetic restorations [5]. It has been verified by Terry [6], 2003 that the understanding of tooth morphology, restorative material selection, color options, and the physical properties of light, allow optimally esthetic restorations to be predictably achieved. Polishing paste Enamelize (Cosmedent INC-Chicago, Ilinóis, EUA) was used with the aid of a felt buff to provide final surface luster and shine
