N S, N M, Shetty A, Kumari A, Dn N - J Conserv Dent (2008)

Bottom Line: To study the concentration of stress in class V restoration of four different restorative materials subjected to occlusal load of 100N, 150N, 200N, 250N and to analyse the obtained data with the listed properties of the restorative material.Within the framework of the aforementioned views, and from the results of the study it can be concluded that microfilled composite is the most suitable restorative material followed by flowable composite, glass ionomer cement and resin modified glass ionomer cement.Restoration of Class V lesions with materials of higher modulus of elasticity will enable better stress distribution.

ABSTRACT

Aim: To study the concentration of stress in class V restoration of four different restorative materials subjected to occlusal load of 100N, 150N, 200N, 250N and to analyse the obtained data with the listed properties of the restorative material.

Materials and methods: Using FEM analysis the stresses generated in a class V lesion in a mandibular premolar was studied.

Results: Within the framework of the aforementioned views, and from the results of the study it can be concluded that microfilled composite is the most suitable restorative material followed by flowable composite, glass ionomer cement and resin modified glass ionomer cement.

Conclusion: Restoration of Class V lesions with materials of higher modulus of elasticity will enable better stress distribution.
