Endoking Dental Resin Composite Heater

Q. What are the advantages of heating composite ?
A. Pre-heating composites improves their handling characteristics, increases flowability, reduces sorption and solubility, enhances marginal adaptability while reducing marginal gaps, and increases microhardness. It reduces the complications that can occur with dental composites, like polymerization shrinkage that can lead to shrinkage stress, in some types or composite without compromising the degree of conversion.

Q. What temperature do you heat composite ?
A. Regardless of how you heat your composite, it’s important to heat your material to at least 60°C (140 F) and place the material shortly after removing the composite from the heat source. As soon as two minutes after it’s been removed, composites loose approximately half of their heat.

Q. Warmed composite will damage my patient’s teeth and gums or will cause sensitivity ?
A. Studies have shown that using composite heated to 60°C results in a less than 1.0°C rise in pulpal temperature ? lower than temperature increases from light curing, and far below the threshold for critical pulpal temperature increase. 

Q. Warmed composite is sticky and more difficult to work with ?
A. Heating composite reduces its viscosity and improves flow, which in turn lowers the force necessary to extrude from the compule. This not only decreases hand fatigue, but also allows for faster, easier, more precise control when placing the material into areas with limited access. And because the composite is more flowable, it?s able to fill all the nooks and crannies of the cavity prep ? enabling less invasive cavity prep with more unique geometries and improved adaption.
