Which motion is used with an enamel hoe during cavity preparation?

The motion utilized with an enamel hoe during cavity preparation is a pulling motion. Enamel hoes are specifically designed to remove enamel and shape the cavity walls by using this pulling action. When the dental professional uses the hoe, they pull it toward themselves, which helps in effectively scraping and smoothing the enamel. This technique allows for precise control over the enamel being removed, ensuring the cavity is prepared properly for the next steps of treatment, such as filling the tooth or placing a restoration.

The use of a pulling motion is critical because it aligns with the instrument's design and intended function, enabling the practitioner to work efficiently and maintain a high level of accuracy in cavity preparation. This contrasts with other motions, which may not align with the ergonomic and functional design of an enamel hoe, making it less effective for this specific task.
