Evaluation of Monomer Leaching from a Resin Cement Through Dentin.

The aim of the study was to evaluate the elution of Triethylene glycol dimethacrylate (TEGDMA), Urethane dimethacrylate (UDMA), Bisphenol A glycerolate dimethacrylate (BisGMA), and Bisphenol A (BPA), from a dual-cured resin cement through human dentin, under constant positive pulpal pressure. Ten human dentin disks were adjusted into a custom made testing device and transparent glass slabs were luted with Variolink II cement, under a steady pressure. The device was filled with Ringer's solution and a pressure of 14.

Evaluation of monomer leaching from a resin cement through dentin by a novel model.

Objective: To evaluate the elution of HEMA, BPA, UDMA and BisGMA from a conventional resin cement (Multilink Automix, Ivoclar Vivadent) through human dentin, under constant positive pulpal pressure.

Methods: Ten human dentin disks (n=10) were adjusted in a new testing device and transparent glass slabs were luted with Multilink Automix resin cement, following manufacturer's instructions, under a steady pressure of 25N. The device was filled with Ringer's solution.
