Restorative dental materials designed to be used as plastic fillings for in situ restoration of the appearance, structure and/or function of a patient\'s teeth. These restorative dental materials consist of a synthetic organic resin matrix in which a blend of particles (e.g., glass, quartz, silica) acting as fillers are dispersed. Composite resin restorative dental materials are supplied in a single-paste or in a two-paste system. They are usually strong, durable, easy to manipulate and shape. Composite resin restorative dental materials are placed in highly visible areas (e.g., the central incisors or any other teeth that can be seen when smiling) or in areas where conservation of tooth structure is a top priority. Heat-cured, self-cured, and light-cured composite resin restorative dental materials are available. They are used in dentists\' offices.
