What is a common use for finishing strips in dental procedures?

Finishing strips are important tools used in dental procedures specifically designed for smoothing interproximal surfaces of restorations. When a filling or restoration is in place, these strips can be used on both the mesial (toward the front of the mouth) and distal (toward the back of the mouth) surfaces to achieve a finely polished finish. This process helps to ensure that the margins of the restoration blend seamlessly with the natural tooth structure and reduces the chance of plaque buildup, contributing to better oral health.

The other choices do not align with the primary function of finishing strips. Applying sealants typically requires different tools, as does holding matrix bands, which involve devices specifically designed for that purpose. Curing dental materials usually involves the use of light-curing devices rather than finishing strips. Thus, focusing on the smoothing function of finishing strips clearly establishes their role in enhancing the surface quality of dental restorations.
