This dosimetric study investigates the impact of scattered and attenuated radiation by dental restorations in head and neck radiotherapy. Dental restorations, including fillings, crowns, and implants, can alter the distribution of radiation doses during radiotherapy treatments, potentially affecting treatment efficacy and normal tissue toxicity. The research employs advanced dosimetric techniques to quantify the extent of radiation scatter and attenuation caused by various types of dental restorations. Through phantom studies and Monte Carlo simulations, the study evaluates the magnitude and spatial distribution of radiation perturbations in the vicinity of dental restorations. The findings contribute to improving treatment planning accuracy and patient safety in head and neck radiotherapy by providing insights into the dosimetric effects of dental restorations.
