Award-Winning Caries Detection

Discover carious lesions in a new way with transillumination technology

Figure 1 | DEXIS CariVu caries detection device is compact, portable, and free of ionizing radiation. Using transillumination technology, clinicians can identify occlusal and interproximal carious lesions, including those that are recurrent, and cracks. This unique technology has been proven to be highly accurate in detecting caries.1 The device illuminates the tooth with near-infrared light that shines through healthy enamel, making it transparent. As lesions are porous, they absorb light and appear as dark areas.

CariVu images look similar to radiographs and read like x-ray images. Unlike fluorescent imaging, there is no need to clean the tooth of bacteria, calibrate the device, or become versed in the meaning of multiple color codes or numeric indicators. Utilizing the award-winning DEXIS Imaging Suite software, CariVu images are displayed on the screen alongside any intraoral x-rays and photos of the same tooth, enabling clinicians to compare them quickly.

CariVu creates a comprehensive patient record that enables clinicians to fully evaluate a tooth’s condition, make a diagnosis, and determine preventive or treatment options. When combined with other images, CariVu images can become part of a historical record for evaluating caries over time. It is also helpful in patients who refuse traditional radiographs for any reason.

CariVu can provide a valuable second opinion when a suspicious area is identified on a radiograph. Its transilluminated image reveals the extent of the condition and helps the clinician determine whether it needs monitoring over time or requires immediate treatment.

1. Identify Lesions
Transillumination technology allows clinicians to identify occlusal, interproximal, and recurrent carious lesions and cracks

2. No Radiation
Emits absolutely no ionizing radiation

3. Early Detection
Routinely finds caries at a much earlier stage compared to x-ray

4. Easy To Use
Compact, portable, and easily incorporated in routine hygiene visits

5. Compare Images
Similar in appearance to radiographs; easily compared to x-ray and camera images in the software
