Radiation exposure during panoramic radiography in children.

Area of Science:

• Radiological protection in pediatric dentistry
• Diagnostic imaging safety
• Radiation dosimetry

Background:

• Panoramic radiography is a common dental imaging technique for children.
• Assessing radiation exposure is crucial for pediatric patient safety.
• Previous studies established radiation levels in adults and phantoms.

Purpose of the Study:

• To quantify radiation exposure in children undergoing panoramic radiography.
• To evaluate the effectiveness of a thyroid collar in reducing radiation dose to the thyroid gland.

Main Methods:

• Dosimeter readings were taken at fourteen anatomical sites on twenty-nine child patients.
• Radiation levels were measured with and without a lead-lined thyroid collar.

Main Results:

• Radiation doses in children were similar to those reported for adults and phantoms.
• Significantly higher radiation doses were recorded in the thyroid area.
• The use of a lead-lined thyroid collar led to a substantial reduction in thyroid radiation doses.

Conclusions:

• Pediatric panoramic radiography yields radiation exposure levels comparable to adults.
• The thyroid gland is particularly susceptible to higher radiation doses during this procedure.
• Thyroid collars are effective in mitigating radiation exposure to the thyroid in pediatric patients.
