Comparison Between the Effect of Using Conventional and Digital Oral Positional Radiation Stent

"Dosimetric analysis: the maxilla (area of the teeth), both parotid glands (ipsilateral and contralateral), the mandible, and the PTV were defined and contoured in computed tomography pre irradiation planning. The mean corresponding dose of each structure were acquired using a dose-volume histogram.~All patients will complete the radiotherapy sessions using the positional radiation prosthesis.~Mucositis assessment: The severity of mucositis will be assessed weekly from the beginning of RT to the end of the treatment (mean time, 7 weeks). It will be scored in accordance with the classification criteria of the National Cancer Institute.~PH of saliva measurement: Collection of saliva sample were done from each patient to measure salivary PH by digital PH meter before beginning of radiotherapy and the measurement will be continued weekly till the end of the treatment."
