Comparison of Stresses Induced by Fiber Post Parapost and Casting Post in Root Canals by Photoelasticity Method

摘要

INTRODUCTIONMany studies have been performed to evaluate the stress distribution around endodontic posts; those which compared posts composed of different materials are rare. The aim of this study was to compare stresses induced in dentin by three structurally different posts using photoelasticity method.
