Introduction: Radiation of the neck and head tumor is the best method for cancer treatment. In this method, the backscattered radiation of dental composites can damage the tissue around it.
Materials and Methods: In this study, the effects of electron beam radiation on healthy teeth were compared to the tooth filled with materials used in dentistry with FLUKA and MCNPX2.6 codes. Simulation was performed for a 8 × 8 × 8 mm cubic tooth composed of Amalgam and Ceramco materials.
Results: The simulation results show that patients with dental caries who inevitably filled their teeth with artificial materials were likely to be exposed to more radiation than other patients were. The results indicate that Ceramco increases the radiation risk for patients more than Amalgam does. Therefore, it is suggested that Amalgam can be considered for filling the caries.
Conclusion: The ceramic material increases the radiation risk for patients more than Amalgam does; therefore, it is suggested that Amalgam be used to fill the caries.
