Which statement is true regarding the surface wear of composite resins under clinical conditions?

When considering surface wear of composite resins under clinical conditions, it’s essential to understand how these materials interact with various factors such as occlusion, patient habits, and the types of opposing dentition.

The correct choice indicates that the first statement about surface wear is true, which typically points to the understanding that composite resins can experience wear over time, often due to their material properties and the forces applied to them during chewing and other activities. The wear rate can vary significantly based on the specific type of composite resin, its formulation, and how it is used clinically.

The second statement being false suggests that there may be misconceptions about the durability or the conditions under which these composites perform. For instance, many might overestimate the longevity of composites compared to other restorative materials like ceramics or metals, not taking into account factors such as wear against natural teeth or potential staining and degradation in certain environments.

Overall, the answer reflects an understanding of both the durability of composite materials and the conditions affecting their performance in a clinical setting, aligning with the true nature of how these materials are functioning in real-life situations.
