Characterization of Oral Stent Stability in a Radiotherapy Environment. RG Price, B Kuykendall, U Parvathaneni, G Sandison. AAPM 2017 Annual Meeting.
An independent study was conducted by the University of Washington's Radiation Therapy Department which showed the GrayDuck Stent to be physically stable and non-deforming over repeated use and irradiation (simulating a course of treatment)
Customized Tongue-Displacing Dental Stents for Oral Mucosal Sparing and Immobilization in Head and Neck Radiotherapy. LR Sales, J Liao, B Johnson, A Winston, G Laramore, U Parvathaneni. ASTRO 2011 Annual Meeting. S493

A study was conducted by the University of Washington's Radiation Therapy Department which showed that customized tongue-displacing oral stents achieved superior oral mucosal sparing compared to what is achievable by conformal planning alone. The authors documented that the stents provided reproducible immobilization, were well-tolerated, and could be readily incorporated into clinical practice. Specifically, the use of custom stents demonstrated that an estimated mean of 10% of the displaced oral mucosal volume avoided exposure to 70 Gy, 22% avoided 66 Gy, 56% avoided 50 Gy, and 79% avoided 35 Gy.
