High-Throughput Evaluation of Restorative Dental Polymers



Sheng Lin-Gibson, Forrest A. Landis, Nancy J. Lin


The effects of co-monomer composition and irradiation time on material properties and cell response were determined using high-throughput and combinatorial methods. 2-Dimensional gradient samples varying in monomer composition and light exposure time were fabricated. The conversion was measured using near infrared spectroscopy (NIR), and the mechanical properties (i.e., hardness and elastic modulus) were determined using nanoindentation. The cell response on gradient samples was also investigated. An excellent correlation was observed between the reaction conversion and mechanical properties as well as the cell response. The ultimate reaction conversion, mechanical properties, and cell response depended on both the co-monomer composition and cure time.
