checkMARC® from BlueLight Analytics is the only professional service (NIST standard) that provides evidence based information to determine the curing time needed based on the curing lights and materials used in your clinic.
A study4 of 915 curing lights in 422 dental clinics found:
These dentists needed to modify their light curing protocols, even between operatories, to reduce recall rates. Some needed at least one new curing light.
The spectrometer-based checkMARC is accurate to within 2% of an Integrating Sphere, the gold standard
in laboratory equipment, according to a study published in the leading scientific journal, Dental Materials. This accurate measurement is then compared to the curing light manufacturer’s specification (the light is just below manufacturer specification in the example at the right).
A checkMARC test provides evidence as to how well the curing light performs when used intra-orally on a larger restoration (e.g., 6 mm diameter) where the surface of the resin composite is at a clinically relevant distance (e.g., 6 mm away from the light tip). The example provided is very common and illustrates that curing light intensity often drops by 50+% over this 6 mm distance.
The checkMARC report provides minimum curing times for the adhesives and resin composites used in that dental clinic. It also warns as to when heat management techniques should be employed. The report can be retained as a reference that this curing light was performing within specification and that the light curing protocols selected by the dentist are aligned with the requirements of the specific dental materials used.
