Caries Detector: Enhancing Precision in Conservative Caries Removal

A SMARTER GUIDE TO SELECTIVE DENTIN EXCAVATION

The modern approach to restorative dentistry emphasizes tissue preservation and clinical precision. Instead of extensive removal, today’s clinicians aim to conserve as much sound and remineralizable dentin as possible.

Caries Detector provides a simple yet effective way to achieve this precision by visually differentiating infected from affected dentin during caries excavation.

UNDERSTANDING THE DENTIN LAYERS

Dentin carious lesion is not homogeneous. It can be divided into two distinct zones:

• Infected dentin — irreversibly demineralized and heavily contaminated with bacteria; must be completely removed.
• Affected dentin — partially demineralized but capable of remineralization; should be preserved to maintain tooth vitality and strength.

The difficulty lies in identifying the exact transition between these two layers. Caries Detector facilitates this decision by providing a visual endpoint for excavation.

MECHANISM OF ACTION

Caries Detector selectively stains the infected outer dentin a vivid scarlet red while leaving the affected and sound dentin unstained.

This clear chromatic differentiation allows clinicians to identify residual infected tissue and avoid unnecessary removal of reparative dentin.

Depending on the clinical situation, the material can be used:

• In shallow cavities, prior to cavity opening for assessment.
• In deep lesions, following initial excavation to guide further selective removal while preventing pulpal exposure.

CLINICAL PROTOCOL

1. Preparation – After rubber dam placement, wash and dry the carious tooth.
2. Application – Place one drop of Caries Detector on a disposable brush and apply to the cavity.
3. Reaction time – Allow ten seconds for staining to occur.
4. Rinsing – Rinse thoroughly with water to remove excess dye and reveal the stained areas.
5. Selective removal – Excavate the red-stained infected dentin with a low-speed rotary instrument, avoiding the unstained tissue.
6. Verification – Repeat application if necessary to ensure complete removal of infected dentin.

The procedure yields a clean, sound dentin surface ready for adhesive bonding and restoration.

INTEGRATING WITH MINIMALLY INVASIVE RESTORATIVE WORKFLOWS

Caries Detector represents the first step in a conservative restorative protocol, aligning with the philosophy of minimum intervention dentistry (MID).

When combined with Kuraray Noritake Dental’s range of adhesive and restorative materials, clinicians can achieve:

• Controlled removal of infected dentin 
• Enhanced bonding to sound, remineralizable dentin
• Optimized aesthetic and long-term restorative outcomes

CONCLUSION

By translating histological principles into a practical chairside tool, Caries Detector allows clinicians to perform caries excavation with greater accuracy and confidence.

It supports minimally invasive principles, preserves tooth vitality, and lays the groundwork for durable, esthetic restorations.

Caries Detector — precision you can see.
