Background: This study evaluates the fracture resistance of pulpotomized primary molars restored with Cermet, Resin modified glass-ionomer cement (GIC), and nanocomposites.
Materials and Methods: A total of 60 primary first and second molars were collected for this study. All the teeth were randomly divided into three groups (N = 20). Standard pulpotomy cavities were prepared. Teeth were air dried and the canal orifices were capped with a layer of zinc oxide eugenol. A lining of calcium hydroxide was placed over it. Cermet, Resin Modified GIC, and nanocomposite were placed in Groups I, II, and III, respectively. All the samples were then subjected to fracture strength test using the universal testing machine, and the results were statistically analyzed.
Results: All the groups were compared by ANOVA one-way test which indicated that there were statistically significant differences among the three groups with P < 0.05.
Conclusion: Nanocomposites can be considered to be a best restorative material in terms of fracture strength among Cermet and Resin modified GIC.
