Introduction: This is the first article of a series of six manuscripts about composite resins. Composite resins composition influence on their physico-chemical properties and increased survive rates of their clinical application in dentistry. Objectives: The purpose of this review was to perform a literature review about the main components found in composite resins and their clinical influence in the restorative process. Methods: A search using several terms was performed on the PubMed database and, after reading the title and abstract, 50 articles were selected. These were read in full and 30 were used in this review. There was also a search in the references of the selected articles. The manufacturer’s technical profile was analyzed for 23 different composite resins. Results: The most of the composite resins are composed of diacrylate monomers (Bis-GMA, UDMA, TEGDMA); zirconium, silica and barium-based are the most cited inorganic particles; and camphorquinone was the most used photoinitiator. Conclusion: The improvements involving components such as organic matrix, inorganic matrix, bonding agent, photoinitiator and inhibitors provided an improvement in the aesthetic quality of the composite resins, which led to their popularization. The composition of the resins is variable and directly interferes with their mechanical and physical properties, also influencing the quality and clinical success of the restorative treatment. Therefore, it is important that this information is clear and available by the manufacturers for the correct clinical application of the material.
