This is the second of six articles that present a general view about composite resins in the last 10 years. The mechanical properties of composite resins show their behavior on clinical situations such as chewing. Therefore, this review commits to evaluate hardness and elastic modulus of these materials and to relate them to success and longevity of restorations. Methods: 60 manuscript were selected for this literature review searched in PubMed platform. This manuscript should contain information of elastic modulus and/or hardness values of commercial resins. Results: The resin with the highest values for both properties was Grandio (Voco GmbH). There was considerable variation in elastic modulus values found for the composite resins. The most cited resins were Filtek Supreme XT (3M / ESPE) ranging from 5.76 to 18.54 GPa, and Grandio (Voco GmbH) ranging from 8.4 to 23.5 GPa. Conclusions: The elastic modulus and hardness of resins are values related to fracture strength or wear and long term stability of this material. Using materials that have adequate values of both properties promote greater quality of the performed treatment. Thus, dentists must have information about the composition and mechanical properties of the resin used, since the composite resin is a material widely used clinically and this subject is directly related to the longevity, success and quality of the restoration.
