Abstract

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.

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.

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.

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.
