NIR images are captured automatically and seamlessly during the scan, from every angle used for the 3D
scanning, and all collected information can then be reviewed using the iTero Element 5D Review tool.
Note:
NIR images should be used in conjunction with the current standard of care for caries detection, and do not
replace it.
The resulting NIRI grayscale image shows structures with varying translucency as different levels of brightness.
The lower the translucency, the higher the reflection of the infrared light and the brighter the structure. Using this
technology, it is possible to make out the following structures:
Appears
Translucency
Enamel
Dark
High
Interproximal caries
Bright
Low
Dentin
Bright
Low
The differentiation between carious lesions and dentin is based upon the location of the bright feature. Dentin is
located in the center of a tooth, whereas interproximal carious lesions appear on the interproximal or distal mesial
region, where healthy enamel is expected.
As such, dentin and interproximal carious lesions appear as bright features, with a dark enamel ring around the
dentin structure, as shown in the figure below, which provides an occlusal view of a carious lesion.
