Seek by Ultradent

SEEK caries (cavity) indicators contain FD&C dyes in a glycol base that stain decayed dentin. SEEK identify caries (tooth decay) in difficult-to-see places. This will prevent over-excavating deep decay and preserve more natural tooth structure. As deeper areas may be able to remineralize, some carious pulp exposures may be prevented. SEEK is also used as a fast, easy way to locate the calcified root canal orifice.

How does SEEK work?

The dyes in SEEK selectively attach themselves to substances of high organic content. SEEK also stains highly permeable, porous materials.

How does SEEK identify calcified canal openings? Does SEEK also indicate higher than normal mineral levels?

A slightly open canal that is difficult to locate will be more visible as the SEEK penetrates the small orifice. Additionally, the tiny amount of organic content in the canal center will stain.

Why is it important to identify and remove not only carious dentin, but dentin lacking in mineral content?

Dentin that is lacking in mineral content is a poor substance to bond to and will affect the integrity of the bond for the entire restoration.

Do you have any information relative to the toxicity of SEEK dyes on pulp?

Dyes used in SEEK are FD&C dyes (food, drug and cosmetic). They have been approved by the FDA in the United States for use in these types of products. We ingest these dyes with our food on a daily basis.
