Summary

This study establishes local reference dose levels for dental X-rays using thermoluminescent dosemeters. Proposed levels are 0.7 mGy for orthopantomography and 3.5 mGy for intraoral radiology, aiding radiation safety in dentistry.

Area of Science:

  • Medical Physics
  • Radiology
  • Radiation Protection

Background:

  • Establishing diagnostic reference levels (DRLs) is crucial for optimizing radiation dose in medical imaging.
  • Orthopantomography and intraoral radiography are common dental diagnostic procedures with varying radiation exposures.
  • Previous dose audits have highlighted the need for localized reference levels tailored to specific equipment and practices.

Purpose of the Study:

  • To determine local reference dose levels for orthopantomography and intraoral radiography based on patient measurements.
  • To critically audit the International Atomic Energy Agency's recommended doses for intraoral X-ray diagnostics.
  • To propose provisional local reference levels for common dental radiography procedures.

Main Methods:

  • Utilized thermoluminescent dosemeters (TLDs) for accurate dose measurements.
  • Conducted patient-based measurements in 11 dentistry installations for orthopantomography.
  • Analyzed data from over 300 intraoral X-ray facilities for auditing purposes.

    • Main Results:

    • Proposed a local reference dose level of 0.7 mGy entrance surface dose (ESD) for orthopantomography.
    • Proposed a local reference dose level of 3.5 mGy ESD for intraoral radiology.
    • Identified variations in doses across different facilities, underscoring the need for local DRLs.

    Conclusions:

    • The established local reference dose levels provide a benchmark for optimizing radiation exposure in dental radiography.
    • The findings support the implementation of tailored radiation protection measures in dental practices.
    • Regular dose audits and adherence to reference levels are essential for patient safety in diagnostic radiology.
