Area of Science:

  • Medical Physics
  • Radiological Dosimetry
  • Diagnostic Imaging

Background:

  • Patient dosimetry is crucial in diagnostic radiography.
  • Panoramic radiography involves radiation exposure to the head and neck region.
  • Accurate estimation of equivalent dose is necessary for patient safety.

Purpose of the Study:

  • To evaluate the dosimetric characteristics of commercial optically stimulated luminescence dosimeters (OSLDs).
  • To estimate the equivalent dose received by patients during panoramic radiography.
  • To assess the suitability of OSLDs for in vivo dosimetry in dental procedures.

Main Methods:

  • Utilized InLight™ OSL nanodosimeters for dose measurements.
  • Employed a digital panoramic unit (Instrumentarium OP200D) with standard exposure parameters.
  • Calibrated dosimeters for air kerma and placed them on the thyroid surface.
  • Measured equivalent doses for male and female adults across different positions and heights.

Main Results:

  • Male adult equivalent doses ranged from 21 to 45 µSv for a standard field of view.
  • Female adult equivalent doses ranged from 28 to 75 µSv for a standard field of view.
  • The lowest dose was 21 µSv (male, thyroid surface, medium height); the highest was 75 µSv (female, parotid surface, small height).

Conclusions:

  • Optically stimulated luminescence dosimeters are appropriate for in vivo dosimetry in dental panoramic radiography.
  • OSLDs provide reliable measurements of patient equivalent dose during these procedures.
  • The findings support the use of OSLDs for monitoring radiation exposure in dental settings.
