Comparison of the shear bond strengths and shrinkage stresses of various domestic composite resins

Abstract

The aim of this study was to evaluate the shrinkage stresses and shear bond strengths of various domestic composite resins by comparing them using Filtek Z-250TM (3M ESPE, USA). In this study, nine domestic composite resins from various manufacturers, Any-ComTM (Mediclus, Korea), Charmfilsup<®>/supPlus (Dentkist, Korea), DenfilTM (Vericom, Korea), ESCom 100sup<®>/sup (Spident, Korea), Hanfilsup<®>/sup (Han Dae Chemical, Korea), Nexcompsup<®>/sup (Metasup<®>/sup Biomed, Korea), Transcensup<®>/sup (Nexobio, Korea), Xsfilsup<®>/sup (B&E Korea, Korea), and Zircos- Comsup<®>/sup (Bioden, Korea), were set as experimental groups and Filtek Z-250TM was set as the control. Of the studied domestic resins, Filtek Z-250TM exhibited the lowest shrinkage stress (p<0.05). ESCom 100sup<®>/sup, Charmfilsup<®>/sup Plus, and Hanfilsup<®>/sup showed shear bond strengths comparable with that of Filtek Z-250TM, whereas the other domestic composite resins exhibited lower shear bond strengths (p<0.05).
