Title Does Polishing An Amalgam Restoration Intraorally Improve The Marginal Integrity Of The Restoration?
Clinical Question In high copper amalgams, does intraoral polishing of the amalgam improve the marginal integrity of the restoration compared to not polishing?
Clinical Bottom Line Polishing the amalgam restoration did not improve the marginal integrity of the restoration, though further studies should be performed. (See Comments on the CAT below)

Comments on
The Evidence
Though the evidence is only from a clinical study and not a randomized control study, systematic review, or meta-analysis, the data is still valid. This study shows that polishing amalgam did not seem to affect the marginal integrity of the restoration one way or another. That doesn’t necessarily mean polishing is a waste of time, only that the effects of polishing were not seen in this study. Further clinical studies should be performed.
Applicability In practice, polishing does not seem to influence the marginal integrity of a high copper amalgam restoration.

I completed a PubMed search on this topic on June 12, 2012. The publication listed in this CAT is still current, the most recent, and the highest level of evidence available at this time.
