Abstract:

Introduction: Radiation therapy is regarded as the mainstay treatment for head or neck cancer patients. In this method, the backscattered radiation of dental composites can damage the surrounding tissue. Material and Methods: The current study compared the effects of electron beam radiation on healthy teeth with the tooth filled with materials used in dentistry with FLUKA and MCNPX2.6 codes. The simulation was performed for a 512 mm3 cubic tooth composed of Amalgam and Ceramco materials. Results: The simulation results indicated that patients with dental caries who inevitably filled their teeth with artificial restorationreceived a more effective dose, as compared to others. Moreover, it was revealed that Ceramco increases the radiation risk more than Amalgam does. Therefore, Amalgam is the right choice for dental filling. Conclusion: Based on the obtained results, ceramic material poses patients to increased radiation risk more than Amalgam does; therefore, it is recommended that Amalgam be used to fill dental cavities.

Effect of dental restorations and prostheses on radiotherapy dose distribution: a Monte Carlo study

Dental restorations, fixed prosthodontics, and implants affect dose distribution in head and neck radiation therapy due to the high atomic number of the materials utilized. The backscatter of electrons from metallic materials due to the impinging treatment x-ray results in localized dose enhancements. These dose enhancements cause localized mucositis in patients who have dental work, a signific...

Monte Carlo Simulation of a Linear Accelerator and Electron Beam Parameters Used in Radiotherapy

Introduction: In recent decades, several Monte Carlo codes have been introduced for research and medical applications. These methods provide both accurate and detailed calculation of particle transport from linear accelerators. The main drawback of Monte Carlo techniques is the extremely long computing time that is required in order to obtain a dose distribution with good statistical accuracy. ...

Monte Carlo study on beam hardening effect of physical wedges

Background: Physical wedges are still widely used as beam modifiers in external beam radiotherapy. However the presence of them in the beam trace may cause beam hardening which may not be considered in many treatment planning systems. The aim of this study is to investigate the beam hardening effect generated by physical wedges via different beam quality indexes as photon spectrum, half value l...
