ABSTRACT: Introduction: This is the fifty of six articles which present a general view about composite resins in the last 10 years. Composite resins were created with the aim of restoring damaged tooth structures, improving function and esthetic of a smile. Despite of their excellent mechanical properties, composites are exposed to different processes of aging in the oral cavity, which can decrease the longevity of the restorations. The aim of this study was to synthesize and describe the main factors related with pigmentation and aging of composite resins and how these factor can influence the material longevity. Methods: After an extensive search in Medline/PubMed using specific terms for each evaluated factor, 32 articles were included in this review. Then, the data extraction and the results evaluation were performed. Results: All evaluated composite resins presented color alteration after pigmentation procedures. The red wine and the coffee were the substances that showed the higher power of pigmentation. On the other hand, for both methods (immersion and photoaging), all composite resins aged with time. Conclusion: The longevity of composite resins is influenced by aging and color alteration caused by pigmentation. These factors must be properly considered and managed by the dentist in order to avoid long-term failure of composite resin restorations.
