Which material is commonly used for anterior composite fillings?

Resin composite is commonly used for anterior composite fillings due to its aesthetic properties and ability to closely match the natural tooth color. The material consists of a polymer matrix combined with ceramic filling particles, providing both strength and a natural appearance, which is particularly important for visible front teeth. Resin composites can be easily shaped and polished to achieve a smooth surface, making them ideal for aesthetic restorations. Additionally, they bond well to tooth structure, enhancing the restoration's longevity and minimizing the risk of leakage and recurrent decay.

In contrast, glass ionomer cement, while useful in specific situations for its fluoride-releasing properties, does not possess the same aesthetic appeal or strength needed for anterior restorations. Zinc oxide-eugenol is typically used for temporary fillings or as a base under more permanent restorative materials but lacks the durability and aesthetics for permanent anterior fillings. Amalgam, though a strong material commonly used for posterior restorations, is not suitable for anterior teeth due to its metallic color, which does not blend with the natural appearance of the tooth. Thus, resin composite stands out as the most appropriate choice for anterior composite fillings.
