Summary

Paediatric panoramic radiography settings significantly reduce radiation exposure for children. Using child-specific programs lowers absorbed doses, regardless of the dental X-ray machine or receptor type employed.

Area of Science:

  • Radiological physics
  • Pediatric dentistry
  • Medical imaging

Background:

  • Panoramic radiography is a common dental imaging technique for children.
  • Optimizing radiation dose in pediatric patients is crucial to minimize long-term risks.
  • Variations in dose exist depending on equipment and exposure settings.

Purpose of the Study:

  • To quantify paediatric radiation doses in rotational panoramic radiography.
  • To compare doses using film/screen and photostimulable phosphor receptors.
  • To evaluate the effectiveness of specific paediatric settings on dose reduction.

Main Methods:

  • Utilized a paediatric anthropomorphic head and neck phantom.
  • Measured absorbed doses on two panoramic systems (Orthophos and PM 2002 CC).

  • Assessed doses with and without programmable child settings, using both receptor types.

    • Main Results:

    • Eye doses ranged from 5 to 24 micro Gy.
    • Paediatric settings generally reduced doses compared to adult settings for both systems.
    • Highest doses were observed near the X-ray beam's rotational axes; lower kVcp or mA settings effectively reduced doses.

    Conclusions:

    • Specific paediatric program settings demonstrably reduce absorbed doses in panoramic radiography.
    • Dose reduction is achieved irrespective of the specific panoramic machine or receptor technology used.
    • Optimized settings are essential for minimizing radiation exposure in pediatric dental imaging.
