Characterization of Extractables from Dental Bite Guards Using GC-TOFMS

In this work, extracts for over-the-counter dental bite guards were prepared and analyzed by GC-TOFMS. The analytical evaluation threshold (AET) was determined and analytes above this threshold were investigated. The Pegasus BTX was used for the initial screen of all samples and the Pegasus HRT+ was used when samples had analytes above the AET without a library identification. The mass spectral data and chromatographic elution information were leveraged to better characterize the chemical composition of these extracts.
