What is used to clean and smooth the floor and walls in cavity preparation?

The enamel hoe is specifically designed for cleaning and smoothing the floor and walls of a cavity preparation in dentistry. Its blade is angled in such a way that it allows for precise control during the shaping process, which is essential in achieving a smooth surface and proper contour of the cavity. This tool is particularly effective for removing any remaining debris or irregularities following the initial preparation of the cavity, ensuring the area is ready for further treatment, whether it is for filling or other restorative procedures.

The enamel hatchet, while useful in cavity preparation, is mainly employed for cutting enamel and helping to refine margins rather than smoothing the surfaces. The mouth mirror serves a different purpose, primarily providing visibility within the oral cavity, but does not actively participate in the cleaning or smoothing processes. The pigtail explorer is utilized for examining the condition of the teeth and detecting cavities or calculus, but it does not contribute to the smoothing of cavity walls or floors. This distinction highlights the enamel hoe's unique role in this specific phase of dental care.
