Area of Science:

  • Biomaterials Science
  • Dental Research
  • Optical Sensing Technologies

Background:

  • Root dentin demineralization is a significant dental concern.
  • Accurate quantification of demineralization is crucial for treatment efficacy.
  • Existing methods for assessing demineralization may be destructive or lack precision.

Purpose of the Study:

  • To develop and validate a novel fiber-optic fluorescence observation (FOFO) technique.
  • To quantify in vitro demineralized human root dentin.
  • To assess the correlation between FOFO measurements and mineral loss.

Main Methods:

  • A fiber-optic fluorescence observation (FOFO) technique was developed.
  • Fluorescein sodium salt was used as a penetrating dye in 40 human root dentin specimens.

  • Excitation at 465 nm and emission at 527 nm were measured, with results corrected and normalized to sound dentin.

    • Main Results:

    • FOFO-values demonstrated a strong linear correlation (r = 0.91) with mineral loss.
    • The technique provides a non-destructive measure of demineralized root dentin severity.
    • The method is applicable to bulk dentin samples.

    Conclusions:

    • The FOFO technique offers a reliable and non-destructive method for quantifying in vitro demineralized human root dentin.
    • This technique shows significant potential for dental research and diagnostics.
    • Further in vivo studies are warranted to evaluate clinical applicability for natural lesions.
