Summary

The goal of this clinical trial is to compare between the Effect of Using Conventional and Digital Oral Positional Radiation Stent on Healthy tissues, salivary PH. The main question it aims to answer are: Does the difference in manufacturing method affect on Healthy tissues, salivary PH.

Participants will use radiation positioning stent during radiotherapy sessions Two groups will be compared

* Group A: OPRS was constructed according to the conventional technique.
* Group B: OPRS was constructed digitally using CAD /CAM technology. to evaluate Dosimetric analysis to quantify the radiation dose in OARs, PH of saliva measurement and Mucositis assessment.

Conditions

  • Radiotherapy Side Effect

Interventions

DEVICE

conventional oral positioning stent were used during radiation planning and the PTV will be defined and contoured in computed tomography pre irradiation planning

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.
