Abstract

The purpose of this study was to evaluate the scatter of light through human teeth with laser Doppler flowmetry. An optical probe (probe 1), which mounted two optical fibers (one for light illumination and another for the measurement of backscattered light intensity) was placed on the labial surface of the extracted teeth. Another optical probe (probe 2) for the measurement of transmitted-light intensity was placed either on the mesial, distal, or palatal surface or in the canal of the teeth. The light intensity at probe 1 was stable, irrespective of the location of probe 2, whereas the transmitted light intensity at probe 2 tended to increase as probe 2 moved to more incisai positions on the mesial, distal, and palatal tooth surfaces. The results indicate that the light scatters to a wide area outside the tooth and provides information regarding the surrounding tissue blood flow.
