BlueCheck® is a detection tool that enables identification of early-stage tooth decay, allowing a prevention approach to heal and preserve the natural tooth structure.

BlueCheck aids oral health professionals to visualize active caries in enamel and dentin.

BlueCheck dental caries detection test kit with a small bottle labeled BlueCheck and a box labeled BlueCheck for early cavity / early caries detection.

BlueCheck makes it possible to detect caries lesions early. This means minimally invasive dentistry approach and cost-effective repair treatments can be used – before cavities develop – potentially preventing painful and expensive surgical dentistry options.

Visual evidence of disease

Simplifies early caries detection with a high contrast blue color at the sites of demineralization to aid visualization of early caries.

Fast and easy to use

With only five simple steps, procedure is less than a few minutes.

It requires no capital equipment, standard armamentarium.

Specific for active caries

BlueCheck specifically binds to surface and sub-surface porosity associated with active caries lesions and turns them blue.

Healthy enamel, arrested caries lesions and exposed root surfaces do not turn blue.

Sensitive detection

BlueCheck can detect lesions as shallow as ~50 microns deep, compared to an radiograph’s detection limit of ~200-400um.

The science behind BlueCheck

Some proteins have a high affinity for the hydroxyapatite that is exposed at sites of dental demineralization. This discovery was used to develop a saline-based caries detection and monitoring device. BlueCheck is a solution containing a biomolecule linked to a dye that binds to the hydroxyapatite exposed in caries lesions. It is designed to give clinicians a direct measure of porosity and disease status.

BlueCheck is applied to the tooth surface, through an electrostatic interaction it binds to hydroxyapatite, after rinsing to wash away any unbound BlueCheck, the remaining blue color is indicative of dental porosity. The deeper the lesion, the more porous area exposed and the darker the blue color (as there is more hyrdroxyapatite for BlueCheck to bind to). Removal of BlueCheck by cleaning with SLS-toothpaste and/or interaction with saliva.

The diagram details the interaction between the protein and dye through a linked pathway and highlights the blue color of the molecule.

BlueCheck Mode of Action

BlueCheck utilises the natural hydroxyapatite-binding chemistry of proteins to specifically and reversibly bind to porous dental hydroxyapatite, enabling direct visualization of dental caries.

Healthy enamel and arrested lesions have little exposed hydroxyapatite for BlueCheck to bind to.

Benefits of BlueCheck to clinical practice

When used during routine dental examinations, BlueCheck helps clinicians:

Patient education tool

Blue color highlights problem areas providing education tool and motivator for patients to improve oral hygiene.

Supports case acceptance

Clear visual evidence supports patient’s understanding treatment plan recommendations and enhances treatment acceptance.

Monitor disease over time

A digital image can record the blue color and BlueCheck can be used to monitor the progress of any intervention.

Enhance oral care outcomes

By catching active caries lesions early, allows a tissue preserving approach to caries management.

Align standard of care

Delivers clinical consistency through an objective visual read-out at active demineralization sites. Allows for standardization of detection and preventive treatment approaches.

Build trust, fostering patient loyalty

BlueCheck’s blue color of the tooth surface provides objective, visual evidence to support the clinician’s diagnosis and treatment decisions.
