  • A- avoid heat generation by using wet polishing paste.
  • B- wait for 24 hours.
  • C- all of the bove.

When polishing amalgam restorations, all of the above are important factors to consider:

A. Avoid heat generation by using wet polishing paste:

Polishing generates friction, which can lead to heat buildup. Excessive heat can damage the amalgam and the surrounding tooth structure.
Using a wet polishing paste helps to dissipate heat and lubricate the polishing surface, minimizing the risk of thermal damage.

B. Wait for 24 hours:

Freshly placed amalgam restorations are still undergoing a hardening process called "setting." Polishing too early can disrupt this process and compromise the final strength and marginal adaptation of the filling.
Waiting at least 24 hours after placement allows the amalgam to fully set, making it more resistant to the pressures and friction of polishing.

C. Combine both practices for optimal results:

Following both these recommendations ensures a safe and effective polishing process that minimizes the risk of damage and maximizes the longevity of your amalgam restoration.

Additional Tips:

Here are some additional tips for polishing amalgam restorations:
  • Use light pressure and a gentle touch.
  • Start with coarser polishing discs or burs and gradually move to finer ones.
  • Avoid polishing for extended periods on any one spot.
  • Rinse the restoration frequently with water to remove debris and cool the surface.

By following these guidelines, you can ensure that your amalgam restorations are polished safely and effectively, helping them to last for many years to come.
