title: Human teeth with and without dental caries studied by visible luminescent spectroscopy.
abstract: The visible emission spectra and fluorescent life-time from decayed and nondecayed regions of teeth were measured and compared. The spectrum from carious lesions is different from that of noncarious tooth regions. This may offer a non-X-ray method for diagnosing dental caries in humans.
