Abstract
Background: This is an in-vitro study done to compare the effect of ferrule on fracture resistance of endodontically treated teeth restored with the glass fiber post cemented with two different esthetic resin modified cements Aim: To compare the fracture resistance of endodontically treated teeth restored with prefabricated glass fiber posts luted with two different resin cements. Materials and methods: Forty-eight freshly extracted maxillary central incisors of similar dimensions were used. The teeth were endodontically treated and decoronated to the level of the facial CEJ. The teeth specimens were divided into two groups of twenty-four each. In both the groups the Bioloren glass fiber posts were used. In Group 1 the posts were cemented with CALIBRA® esthetic resin system. In Group 2 the posts were cemented with SMARTCEMTM2. Cores were built using composite resin material. The teeth were then embedded in auto polymerizing acrylic resin blocks. The specimens were subjected to loading in a universal testing machine. The data obtained was subjected to statistical analysis. Results: The fracture resistance was higher for group 2 teeth with a mean ±SD of 2744±452.56340. The failure load observed in Group 1 was lower with a mean ±SD of 2178±452.56344. The one way ANOVA showed that in both the groups resin modified cements (Calibra® esthetic resin cement andSmartCemTM2) highly significantly influenced the resistance of the specimen to fracture under static loading (P < 0.002 and P <0.001 respectively). Conclusion: The inherent strength of the SmartCem™2 enhanced stability and strength of the overall restoration when compared to Calibra®. Further studies should incorporate thermal cycling of the specimen and cyclic loading, stress distribution patterns, photo elastic analysis, finite element analysis and model studies to achieve better results.
