Primary outcomePrimary: Time Until the Maximum Oral Mucositis Measured From the Start of Radiation Treatment. — 34; 29 Days — p=0.9906
Summary
The main objective of this study is to determine the feasibility of optimizing the IMRT treatment plan based on dosimeter measurements of mucosal radiation dose adjacent to the dental fillings to reduce such dose to < 35 Gy without compromising tumor coverage and/or increasing the dose to the remaining oral cavity or nearby parotid glands.
