- Abstract
Purpose: The main objective of this study is to develop a substance that can enhance the absorption of radiation therapy for head and neck cancer and protect the surrounding tissues of the tumor during radiotherapy. Materials and Methods: The dimensions of the specimen are 40 mm x 55 mm in length and width, with a thickness of 6 mm based on Iraqi population studies. The sample was composed of four groups, A, B, C, and D. Each group was exposed to two different types of energy, 4 MEV, and 9 MEV, by the VARIANI X2300 radiation machine. Results: The amount of radiation penetration was measured and statistically analyzed using Levene's and two-way ANOVA tests to determine the differences and identify the best materials. The data from this study show a highly significant difference (p-value < 0.001) in radiation penetration between all groups. Conclusion: The stent made with a combination of cold-cure acrylic and tungsten alloy has the lowest radiation penetration at 4 MEV and 9 MEV energy levels, making it the best material stent for protecting healthy tissues against radiation. On the other hand, stents made solely with cold-cure acrylic offer poor radiation protection.
