N1a: Chemical Emissions and Inhalation Risks Associated with Resin 3D Printing in Dental Fields

Ernest N. Morial New Orleans Convention Center 

Resin 3D printing has been widely used in dental fields including dental schools and clinic offices. However, the liquid resins may contain irritating or sensitizing components that can off gas during normal use or even at room conditions. This may pose inhalation risks for users who handle resins daily as well as bystanders in the room during normal work hours.

This study developed a method to screen for volatile organic compound (VOC) emissions from commonly used dental resins and assessed the potential inhalation risks associated with these resins.
