OCT enhances artificial dental alterations with greater detail

Sept. 9, 2015
A study has shown that optical coherence tomography (OCT) enhances morphological changes in human teeth.

An in vitro study of morphological alterations between sound dental structure and artificially induced white spot lesions in human teeth was performed through the loss of fluorescence by Quantitative Light-Induced Fluorescence (QLF) and the alterations of the light attenuation coefficient by Optical Coherence Tomography (OCT).

Our take:

An international team of researchers from the State University of Paraíba (Campina Grande, Brazil), the Federal University of Pernambuco (Recife, Brazil), the Nuclear and Energy Research Institute (IPEN-CNEN/SP; São Paulo, Brazil), and the Karolinska Institute (Solna, Sweden) compared a quantitative fluorescence technique with optical coherence tomography (OCT) to analyze morphological alterations between sound dental structure and artificially induced white spot lesions in human teeth. Results showed that OCT enhanced the tooth alterations more than the fluorescence technique did.
