What is the primary use of pear-shaped burs?

1. To create undercuts in cavity preparations

2. To provide initial cuts for cavity preparations

3. For moderate to large occlusal caries

4. To finish restorations

The correct answer is: For moderate to large occlusal caries

The primary use of pear-shaped burs is specifically tailored for moderate to large occlusal caries. These burs are designed to effectively remove decay and prepare larger cavities in the occlusal surfaces of teeth. Their unique shape and design allow for efficient cutting and shaping of the tooth structure, making them particularly useful when addressing significant carious lesions. While other choices may describe functions that some burs can perform, pear-shaped burs are predominantly recognized in dental practice for their role in handling moderate to large cavity preparations. Other types of burs are more suited for tasks like creating undercuts or finishing restorations, but pear-shaped burs excel in the initial preparation phase for substantial carious lesions.
