Abstract
- Oral squamous cell carcinoma is the sixth most common cancer reported globally, with an annual incidence of over 300,000 cases, of which 62% arise in developing countries. Radiation therapy is a treatment modality that uses ionizing radiation as a therapeutic agent. It is widely employed in the treatment of head and neck cancer, as a primary therapy coupled with surgical procedure and chemotherapy or as a palliative treatment for advanced tumors. However, radiotherapy can cause a series of complications such as xerostomia, mucositis, osteoradionecrosis, and radiation caries. Composite circular disc containing different ratios of acrylic and barium sulfate (BaSO<subscript>4</subscript>) were made in-house. The purpose of this study was to evaluate the percentage attenuation from these composite shields in <superscript>60</superscript>Co gamma rays. A maximum of 8% radiation attenuation was achieved using 1:4 ratio of acrylic-BaSO<subscript>4</subscript> composite shields. The study proposes BaSO<subscript>4</subscript> as one of the compounds in combination with acrylic resin or any other thermoplastic substances for making biocompatible radiation attenuating devices.
