Evaluation of commercial and newly-synthesized amine accelerators for dental composites

The characteristics of newly synthesized tertiary aromatic amines as accelerators for restorative resins have been evaluated. Comparison of the composites prepared with these and presently used accelerators indicate that resins formulated with 4-N,N-dimethylaminophenylacetic acid, its methyl ester or N,N-dimethylaminoglutethimide have properties generally better than comparable resins prepared with commercially used amines.
