What is the use of a narrow spatula in dental practices?

1. To carve amalgam on the occlusal surface

2. To mix rubber base or stone

3. To hold matrix band in place

4. To dry root canal

The correct answer is: To mix rubber base or stone

The narrow spatula is commonly used in dental practices primarily for mixing materials, such as rubber base for impressions or dental stone for casts. Its design, which typically features a flat, narrow blade, allows for precise control when combining powder and liquid components, ensuring an even mix is achieved. This is crucial in achieving the right consistency and properties for the materials, which can affect the outcome of procedures, such as creating accurate dental casts or impressions. While other instruments may be better suited for the specific functions described in the other options, the narrow spatula's role in the mixing process is fundamental and highlights its essential place in dental procedures. Its utility in handling both rubber base and stone makes it an indispensable tool in ensuring that these materials are prepared effectively before use.
