What does the term 'ceramic' refer to in the context of dental materials?

1. A hard brittle material from non-metallic substances

2. A soft flexible material for impressions

3. A type of anesthesia used in dental work

4. A substance used in tooth whitening

The correct answer is: A hard brittle material from non-metallic substances

The term 'ceramic' in the context of dental materials refers to a hard, brittle material that is derived from non-metallic substances. Ceramics are commonly used in dentistry due to their favorable properties, such as high strength, aesthetic appeal, and biocompatibility. They are often utilized in the fabrication of restorative materials like crowns, bridges, and veneers because they can closely mimic the appearance of natural tooth structures. The durability and resistance to wear make ceramics an ideal choice for dental applications where strength and aesthetics are crucial. In contrast, the other options pertain to different aspects of dental materials or practices, such as soft flexible materials used for impressions, types of anesthesia for pain management during dental procedures, and substances implemented in tooth whitening, which do not align with the definition or application of ceramics in dentistry.
