Area of Science:

  • Medical Physics
  • Radiological Dosimetry

Background:

  • Electron paramagnetic resonance (EPR) dosimetry using tooth enamel is a method for retrospective dose assessment.
  • Accurate dose estimation requires detailed models of tooth anatomy and phantom geometry.

Purpose of the Study:

  • To develop detailed mesh-type tooth models for use in computational phantoms.
  • To calculate tooth enamel doses using Monte Carlo simulations for external photon exposures.
  • To investigate the influence of phantom age, sex, and tooth site on enamel dose.

Main Methods:

  • Development of 198 detailed mesh-type tooth models across various age groups and sexes.
  • Implantation of tooth models into International Commission on Radiological Protection (ICRP) pediatric and adult reference computational phantoms.
  • Monte Carlo simulations using Geant4 to calculate tooth enamel doses for external photon irradiation.

Main Results:

  • Low-energy photons (<0.1 MeV) showed significant dose variations (orders of magnitude) based on age, sex, and tooth site.
  • Photon energies between 0.1 and 3 MeV had minimal impact from these parameters.
  • High-energy photons (>3 MeV) resulted in moderate differences (up to a factor of two) due to dose build-up.
  • Comparison with previous studies using less detailed models revealed substantial discrepancies, especially at low energies.

Conclusions:

  • The detailedness of tooth models significantly influences low-energy photon dosimetry results.
  • Age, sex, and tooth site are critical factors for accurate EPR dosimetry at low photon energies.
  • The developed detailed models provide a more refined approach for retrospective dose assessment in tooth enamel.
