Seek (Ultradent) – Caries and Canal Orifice Indicator

Seek from Ultradent is a high-contrast red dye, specifically developed as a multifunctional diagnostic aid in dentistry. It is supplied in a convenient $1.2 \text{ ml}$ syringe form, ensuring accurate and controlled application.

Technology and Dual Purpose

1. Caries Indication: Seek is a selective caries indicator used to accurately distinguish between healthy, remineralized, and infected dentin. The red dye penetrates and stains the denatured collagen fibers in the infected dentin, which have a looser structure. Healthy dentin, due to its dense, mineralized structure, remains unstained. This provides the clinician with visual control for performing minimally invasive preparation, preserving the maximum amount of viable tooth structure and protecting the pulp from damage.

2. Root Canal Orifice Localization (Endodontics): In endodontic practice, Seek is used for the quick and clear identification of root canal orifices. The red color creates a bright contrast against the background of the pulp chamber floor, especially in complex cases, such as the presence of calcifications or resorption. Applying the indicator helps visualize the canal entrances, simplifying access and reducing the risk of perforation.

Advantages of Use

• High Contrast: The red color ensures excellent visibility both in carious cavities (especially against light dentin) and in pulp chambers.

• Accuracy and Safety: The selectivity of the staining helps avoid excessive removal of healthy tissues, which is critically important for successful long-term treatment.

• Ergonomics: The syringe with a fine cannula allows the material to be applied directly to the working area with minimal waste.

• Versatility: The dual application (caries and endodontics) makes it a universal tool in daily practice.

Seek is an indispensable diagnostic tool that enhances the accuracy and efficiency of both restorative and endodontic procedures.
