| Title |
Effects Of Pre-Heating Resin Composite On Adaptation And Adhesion To teeth |
| Clinical Question |
Does pre-heating resin composite before placement increase the adaptation and adhesion to the teeth better than standard room temperature resin composite? |
| Clinical Bottom Line |
This trial shows that pre-heating resin composites may increase adaptation and decrease microleakage at the cervical margins, but not at the occlusal margins. (See Comments on the CAT below) |

Comments on
The Evidence |
The evidence is not strong considering the study type and that no other trials were found. |
| Applicability |
This could significantly decrease the incidence of microleakage and secondary caries assuming the information is correct and more in-depth research were performed to verify the findings. Seemingly simple to do, pre-warming the resin composite may be fairly easy to implement in private practice. |

In April 2011, Deb S published an article titled "Pre-warming dental composites" (PMID#: 21145580). This study was a combination of an in vitro and clinical trial. They found that the only property affected by pre-warming the composite was increased flowability. All other properties, including micro leakage, showed no significant differences. | |
