Which type of dental instrument is used for cavity preparation?

The instrument primarily used for cavity preparation is the drill. This tool, often referred to as a dental handpiece, allows dental professionals to efficiently remove decayed or damaged tooth material to prepare the cavity for filling. The drill operates at high speeds and can be fitted with various types of burs, each designed for specific tasks, such as creating access holes or refining cavity walls. Its precision is critical in ensuring that the preparation is adequate for the successful placement of restorative materials.

While other instruments do have important roles within dental procedures, they are not intended for the process of cavity preparation. For instance, an explorer is used mainly for examining the tooth structure to diagnose caries or other issues. A scaler is utilized for removing calculus and plaque from the teeth, aiding in periodontal health rather than restorative procedures. Forceps are designed for the extraction of teeth, which is a different aspect of dental care altogether. Thus, the drill stands out as an essential tool specifically for preparing cavities in dentistry.
