Near-Infrared Imaging of Artificial Enamel Caries Lesions with a Scanning Fiber Endoscope.

The intensity difference measurements ( Table 2 ) between dry and wet measurements and lesion contrast values ( Table 2 and Figure 6 c,d) showed an increasing trend with an increase in lesion depth and severity; these measurements did not yield as significant results as the raw intensity measurements taken from the dry condition suffered from high variance.
