Frequently Asked Questions

The shelf life of OMNICHROMA FLOW and BLOCKER FLOW is 3 years from date of manufacture.

For optimal performance, please store product in a cool, dark space kept at a temperature between 32-77 degrees.

No, OMNICHROMA FLOW and BLOCKER FLOW are only available in syringes of 3g(1.8mL).

OMNICHROMA FLOW and BLOCKER FLOW contain 71% by weight (57% by volume) of spherical silica-zirconia filler and composite filler.

Structural Color Technology is a replication of structural color, a naturally occurring phenomenon seen in morpho butterflies, peacocks, surfaces of CDs, bubbles, etc. When different wavelengths of light are amplified or weakened by the structure of the material itself, the material will express colors other than what the material may actually be. For example, if we strip away the light and magnify the surface of a peacock feather, they appear brown. However, when we see the feather naturally, the light is manipulated and our eyes perceive it as the beautiful, metallic looking blues and greens. OMNICHROMA product family is the first to utilize structural color science rather than rely on dyes and pigments to color-match.

OMNICHROMA FLOW’s recommended depth of cure is the standard 2mm. OMNICHROMA FLOW works just like any flowable composite you have previously used, just simplified. To restore cavities of more than 2 mm depth, you can work in layers.

Because of OMNICHROMA FLOW’s supra nano spherical fillers, OMNICHROMA has the strength and durability needed for posterior restorations, as well as the polishabilty and esthetics suited for anterior restorations. OMNICHROMA FLOW is truly a universal one-shade flowable composite.

• All cases of direct anterior and posterior restorations

• Cavity base or liner

• Repair of porcelain/composite

No, any bonding system designed for use with resin composites works well with OMNICHROMA FLOW. However, we do recommend Tokuyama Universal Bond, which is the first and only self-cure universal adhesive capable of achieving superior bond strength to all dental materials while following the same, quick and easy, 25-second protocol for every application. It saves time by eliminating the need for etching; surface agitation; light-curing; and does not require the use of any
additional primers or activators. Tokuyama Universal Bond
virtually eliminates post-op sensitivity

Due to OMNICHROMA FLOW’s Structural Color Technology, OMNICHROMA FLOW will always adapt to shade of the tooth structure it is bonded to. So, whether your patient’s teeth darken over time or if they want to bleach, OMNICHROMA FLOW will shade-match the changing teeth. There is no need to replace the composite!

There are no case OMNICHROMA FLOW is not suited for. It is truly a one-shade flowable composite.

There is no shade that we do not recommend for OMNICHROMA FLOW because it matches to the natural red-to-yellow color spectrum that all teeth possess. As long as there is surrounding tooth structure OMNICHROMA can be bonded to, OMNICHROMA will be able to reflect the shade. In cases where there is little to no surrounding tooth structure, we recommend using OMNICHROMA BLOCKER FLOW.

You do not have to use BLOCKER FLOW in most cases for OMNICHROMA FLOW to work. BLOCKER FLOW is a supplementary material to be used in conjunction with OMNICHROMA FLOW as a lingual layer to prevent shade-matching interference in certain cases, such as extensive class III and IV restorations. OMNICHROMA BLOCKER FLOW can also be used to mask staining, dark dentin, or to reconstruct a highly opaque tooth.

The curing time of OMNICHROMA FLOW varies according to the relationship between light intensity and increment depth.
See chart below:


The curing time of BLOCER FLOW varies according to the relationship between light intensity and increment depth.
See chart below:


Yes. We recommend 5 seconds or more light irradiation with a high intensity curing unit. See the table in the manufacturer’s instructions for use (IFU) for reference. An adequate depth of cure can be obtained even with 3 seconds on the data, however when the light irradiation time is shorter than 3 seconds, the clinical technique sensitivity will be higher, therefore we recommend 5 seconds or more.

Any polishing kit will work well with OMNICHROMA FLOW.


It is 0.9mm (Gauge: 20G).


OMNICHROMA FLOW does not contain Bis-GMAs, however BLOCKER FLOW does.
