ABSTRACT


Aim

The purpose of this finite element analysis (FEA) study is to evaluate and compare the stress distributions at the
primary molars and restorative materials according to the material used.

Methods

A total of 12 3D models of
Class II cavities in primary molars plus one control model were analysed. Study Design: Three-dimensional FEA was used to compare
stress distribution on enamel, dentin and restoration surfaces of cavities. Statistics: Stresses occurring under occlusal forces were
compared with the von Mises criterion.

Results

The highest von Mises stress values at the enamel and restoration of restored tooth
84 were computed. On the basis of these results, all materials were ranked on enamel stress as: flowable composite resin (FCR)>
compomer > resin modified glass ionomer cement (RMGIC) > giomer composite resin (GCR) > hybrid composite resin (HCR) > amalgam.
Moreover, ranking of materials on restoration stress was FCR < compomer < RMGIC < GCR < amalgam < HCR.

Conclusion

A
restorative material with appropriate elasticity module, able to balance stress concentrations, should be used to increase the survival
rate of both the hard tissue of the tooth and the restoration material.
