Which of the following materials is commonly used for dental restorations?

Composite resin is commonly used for dental restorations due to its aesthetic appeal, versatility, and bonding capabilities. It allows for tooth-colored restorations that blend well with natural teeth, making it a popular choice for visible areas. Additionally, composite resin can be molded to match the shape of the tooth, providing a more natural appearance.

This material also offers excellent adhesion to tooth structure and can help reduce microleakage, which is important for the longevity of restorations. Furthermore, composite resins can be used for a variety of restorative procedures, including fillings, chips, and even veneers, making them a widely accepted and adaptable option in dental practice.

While gold foil, amalgam, and glass ionomer cement are also used for dental restorations, they may serve specific niches or requirements that composite resin can meet across a broader range of situations, particularly in aesthetic dentistry.
