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)

#1) 18335736Wagner/200840 extracted third molarsIn vitro randomized controlled trial
Key resultsNo statistical differences were observed among materials at the occlusal margin. Preheating the composite resulted in significantly less microleakage at the cervical margins compared to the flowable liner and control. p<0.05

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.
