Which bonding agent is commonly used with composite materials?

Dental adhesive systems are commonly used with composite materials due to their ability to create a strong bond between the tooth structure and the composite filling. These adhesive systems often consist of multiple components that may include etchants, primers, and bonding agents, which work together to enhance the adhesion of the composite to the tooth. The bonding agents in these systems penetrate the smear layer on the tooth surface, helping to provide a micromechanical retention that is crucial for the long-term success of composite restorations.

In contrast, glass ionomer cement is typically used in situations where fluoride release is beneficial, such as for root caries or when a good seal against dental decay is necessary, but it does not bond as effectively to composite materials as dental adhesives do. Polycarboxylate cement is generally used for cementing crowns and bridges rather than for bonding composite materials, due to its different properties and lower strength. Hydraulic calcium silicate is primarily used for pulp capping and preserving tooth vitality rather than bonding composite materials securely.
