eek and Sable Seek identify demineralized dentin in difficult-to see places—for example, under the overhanging enamel of Class I, II, or III preparations, or along the DE junction of the preparation. Green Sable Seek helps prevent overexcavating deep caries, which can lead to pulp exposure. Nonmineral dentin should be removed to improve the bond strength of the entire restoration. Red Seek is easily visible on dark dentin and provides a fast, effective way to locate calcified root canal orifices.
