Evaluation of Monomer Leaching from a Resin Cement Through Dentin

doi: 10.1922/EJPRD_01854Kerezoudi08

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 14.1 cm H2O was applied. Eluates were
retrieved from each one of the ten specimens at 9 time intervals. All the samples were analyzed
by High Performance Liquid Chromatography (HPLC). TEGDMA was detected from the second
and UDMA was detected from the fourth time interval. The highest average concentration of
TEGDMA and UDMA was detected in the 3 day time interval. Time had a significant effect on
their elution. BPA and BisGMA were not detected in any sample at any time interval. The clinical relevance of the present study is that the concentration of the eluted monomers, under the
conditions that were chosen, did not reach toxic levels for the pulp.
