What is the main purpose of burnishing in dentistry?

The main purpose of burnishing in dentistry is to condense margins. This technique involves the use of a burnisher, which is a smooth, rounded instrument that is used to apply pressure to the surface of a filling material or dental restoration. By doing so, burnishing helps to create a tighter seal between the restorative material and the tooth structure, reducing the risk of marginal gaps that could lead to secondary caries or other dental issues.

Furthermore, the process of burnishing can lead to improved surface characteristics of the restoration, enhancing its durability and longevity. Properly condensed margins are crucial for maintaining the integrity of the restoration over time, ensuring that it remains effective in its function and aesthetically pleasing for the patient.

While other options might relate to aspects of dental procedures, they do not capture the specific purpose of burnishing as effectively as condensing margins does. For instance, while burnishing may help polish filling materials to some extent, its primary goal is related to ensuring a proper fit and seal at the margins of restorations. Similarly, enhancing adhesion of composite resins is not the primary focus of burnishing; rather, that would typically involve specific bonding agents and techniques.
