ABSTRACT

These tests showed that DMBA, a recently commercialized amine accelerator, is more suitable from the standpoint of color for use in denture base, reline, and repair resins than is the commercially used amine, DMPT. As the curing times of all specimens were approximately the same, the mechanical properties are expected to be similar for the following reasons. Previous experiments have shown that in the same composite formulation, equimolar concentration of DMPT and DMBA produce identical hardening times. A more recent investigation with composite systems indicates that amines yielding comparable polymerization rates produce materials with approximately the same mechanical strength; the same is expected to prevail with unreinforced methacrylate polymers. All specimen disks provided similar resistance to bending by hand.
