Estimation of radiation dose from porcelain teeth containing uranium compound

Area of Science:

• Dental Materials Science
• Radiological Health

Background:

• Porcelain dental restorations are common.
• Understanding their elemental composition is crucial for safety assessments.

Purpose of the Study:

• To quantify uranium concentrations in various brands of porcelain teeth.
• To estimate the radiation dose to oral tissues from this uranium.

Main Methods:

• Fission track analysis was employed to determine uranium content.
• Dose equivalent calculations were performed for oral mucosa exposure.

Main Results:

• Uranium concentrations varied significantly between brands, ranging from 0.33 to 205 ppm.
• Calculated dose equivalents provide an estimate of potential radiation risk.

Conclusions:

• Porcelain teeth exhibit a wide range of uranium concentrations.
• Further research may be needed to establish safety thresholds for oral radiation exposure from dental materials.
