Your Lights. Your Materials. Your Curing Times.

How well does your curing light perform?


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.

Fast Facts About Light Curing

  • Half of all dental income1 relies on the successful use of light-cured dental materials.
  • Every brand and shade of resin composite requires a speci c “dose” of blue light to polymerize.
  • Incomplete polymerization leads to increasing clinical problems2,3 (e.g., fracture, secondary decay, de-bonding, discoloration) and post-op sensitivity.
  • The heat produced from high-powered curing lights can quickly harm soft tissues and tooth pulp2,3.

73% Need to Make Changes

A study4 of 915 curing lights in 422 dental clinics found:

  • 30% delivered less than half of the energy dose required by the selected dental material.
  • 43% used extended curing times (to ensure an adequate cure), unknowingly risking heat damage.
  • Curing times ranged from 3 – 90 seconds, regardless of the material selected by the dentist.

These dentists needed to modify their light curing protocols, even between operatories, to reduce recall rates. Some needed at least one new curing light.

Advantages of the checkMARC Service


Scientifically Accurate

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).

Clinically Relevant

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.

Clinic Specific

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.
