Abstract
To analyze and compare stress distribution in class V restoration with different restorative materials using finite element analysis. 3D model of upper first premolar was created, which was then altered to accommodate Class V cavity of fixed dimension. The restoration was done with four different materials i.e microfilled composite, flowable composite, glass ionomer cement and resin modified glass ionomer cement. The restored model was subjected to a force of 100N, 150N, 200N, and 250N at right angles to the buccal cusp. Stresses were analyzed and compared in different materials and tooth tissues both. From the biomechanical point of view, the restorations of class V defects are important and the best clinical approach would be to apply restorative materials, which have large Young’s moduli`
