    Area of Science:

    • Medical imaging technology
    • Biomedical engineering
    • Radiation physics

    Background:

    • Patient immobilization is crucial for high-quality medical imaging, particularly in computed tomography (CT).
    • Conventional immobilization devices may interfere with imaging or pose safety concerns.
    • Metal dental restorations can cause artifacts and increase radiation dose to oral tissues during CT scans.

    Purpose of the Study:

    • To develop and describe an all-plastic bite-block for patient immobilization during CT scanning.
    • To evaluate the impact of the plastic bite-block on CT image quality.
    • To present a method for reducing radiation dose to the buccal mucosa from dental fillings.

    Main Methods:

    • Construction of a novel bite-block using only plastic components.

  • Integration of the bite-block into the CT scanning procedure.
  • Description of a technique to minimize electron backscattering from metallic dental restorations.

    • Main Results:

    • The all-plastic bite-block was successfully constructed and utilized in CT scans.
    • No detrimental effects on CT image quality were observed with the use of the apparatus.
    • A method was detailed to reduce electron backscattering onto the buccal mucosa.

    Conclusions:

    • An all-plastic bite-block is a viable and safe option for patient immobilization in CT scanning.
    • The proposed design does not compromise diagnostic image quality.
    • The technique for reducing electron backscatter offers improved radiation safety for patients with dental fillings.
