Which finishing stone is suitable for removing a submarginal area in amalgam polishing?

The white finishing stone is particularly suitable for removing submarginal areas during the polishing of amalgam. This finishing stone is designed to refine and smooth the surface of dental restorations, creating a polished finish that enhances both esthetics and functionality.

The white finishing stone is typically made of a finer abrasive material, which allows for a smoother finish without excessively removing material. Its use is ideal for adjusting and polishing amalgam restorations, especially in areas where precision is vital for a good marginal seal and overall restoration integrity.

Other tools, such as the tapered and flame burs, while useful in shaping and contouring, may be too aggressive for the final polishing stage and can inadvertently remove more material than desired. The green finishing stone, while useful for initial shaping, is not as effective for the fine detailing required in the polishing step after achieving the desired contour. Hence, the white finishing stone stands out as the preferred choice for this specific task in dental care.
