Background: Causes of failures in class V restorations have always been controversial until now since the biomechanical aspects of these restorations have been understood.

Aim: To comparatively evaluate the stress distribution of a class V restoration in a lower first premolar using a two-dimensional plane strain finite element model.

Materials and Methods: The study was done by modelling a mandibular first premolar which was sectioned buccolingually, in the Ansys 14.5 finite element software. A 100N eccentric load was applied on the tooth structure and stresses were observed at the peripheries of the class V restoration when it was restored with Centurion N, Giomer and Ketac N100 respectively. Finite element analysis has been used to evaluate the stress distribution.

Results: Alkasite glass ionomer cement & Nanohybrid composite values were comparable to withstand masticatory forces but depicted significantly higher resistance to masticatory load when compared to nano-filled resin-modified glass ionomer cement.

Conclusion: Alkasite glass ionomer cement & Nanohybrid composite are suitable restorative material for class V restorations because of low-stress transfer to the tooth.
