Transillumination

Many caries detection systems have been developed to detect caries in early stages when surgical interventions can be avoided. Although many of these systems have been based on measuring a physical signal that serves as an indicator of caries, transillumination allows for direct 3-dimensional optical visualization of the caries lesion itself. Transillumination uses the principle that light transmission differs between caries or demineralized enamel, which appear darkened, and sound enamel or dentin, which is transparent.
