What is the main purpose of straight fissure burs?

To remove caries
To create smooth walls in cavity preparations
To finish restorative work
To cut tooth structure

The correct answer is: To cut tooth structure

The primary purpose of straight fissure burs is to cut tooth structure. These instruments are designed with a straight, cylindrical shape that allows them to efficiently penetrate and remove hard dental tissues, such as enamel and dentin. The design facilitates the creation of precise cuts, making them essential tools for dentists when preparing cavities or shaping tooth surfaces. This cutting ability is crucial during various dental procedures, including cavity preparation and the initial shaping of tooth structure. Although they may indirectly assist in removing caries or creating smooth walls, the fundamental function of straight fissure burs is centered around their capacity to cut and shape tooth structure, which includes efficiently preparing a cavity for restorative work.
