**Core Concept**
Cutting and grinding procedures in dentistry involve the removal of tooth structure using various hand instruments or rotary tools. This process is essential for preparing teeth for restorations, removing decay, or shaping the tooth for optimal oral function and aesthetics.

**Why the Correct Answer is Right**
The correct answer involves the use of **diamond burs**. Diamond burs are predominantly used for cutting and grinding procedures due to their unique properties. They are made from industrial diamonds that are bonded to a metal substrate, allowing for the efficient removal of hard tooth structure. The diamond particles on the bur are responsible for the cutting action, and the metal substrate provides strength and durability to the instrument.

**Why Each Wrong Option is Incorrect**
**Option A:** Carbide burs are not predominantly used for cutting and grinding procedures. While carbide burs are used in dentistry, they are more commonly associated with cutting and shaping hard tissues such as bone or orthodontic appliances.

**Option B:** Ceramic burs are not suitable for cutting and grinding procedures due to their brittle nature and tendency to fracture. They are more commonly used for polishing and refining surfaces.

**Option C:** Steel burs are not typically used for cutting and grinding procedures in dentistry. They are often used for rough shaping or cutting through soft tissues such as bone or periodontal tissue.

**Clinical Pearl / High-Yield Fact**
When selecting a bur for cutting and grinding procedures, it is essential to consider the type of tooth structure being removed and the desired outcome. Diamond burs are ideal for removing hard tooth structure, while carbide burs are better suited for cutting through softer tissues.

**Correct Answer: C. Diamond burs.**
