| Title |
Pin-Retained and Bonded Amalgam Restorations Show Similar Clinical Failure Rates |
| Clinical Question |
How does the clinical failure rate of bonded amalgam restorations compare to mechanically retained amalgam restorations for healthy adult patients? |
| Clinical Bottom Line |
There is no statistically significant difference in failure rate between pin-retained amalgam restorations and bonded amalgam restorations. (See Comments on the CAT below) |

Comments on
The Evidence |
As time progresses and more data become available, further research should be conducted to substantiate this conclusion and perhaps identify specific scenarios (i.e., less than ideal isolation) in which the use of bonded amalgam may be contraindicated. |
| Applicability |
This information is highly applicable due to the relatively recent introduction of bonded amalgam restorations into the clinical setting and its rapid replacement of traditional mechanical retention features in many posterior restorations. At this time it appears that bonded restorations provide similar retention as compared to amalgam restorations that employ mechanical retention features. |

I conducted a PubMed search related to the subject of this CAT April 2012 and I found a more recent publication that backs the findings of the published CAT to a certain extent. PubMed ID: 19821423.
