A COMPARATIVE STUDY TO EVALUATE THE FRACTURE RESISTANCE EFFICIACY OF THREE DIFFERENT LUTING AGENTS USED FOR ADHESION OF POST IN ENDODONTICALLY TREATED TOOTH

Due to the carious processs peripheral destruction and the endodontic treatments central destruction, the majority of endodontically treated teeth are structurally compromised and weaker. In an effort to strengthen the tooth a post was placed to hold the core material in place when there was not enough clinical crown left. Thus the main Aim : of our study was to compare and evaluate the efficacy of three different luting cements to hold these core materials in place. Material And Methodology: 30 freshly extracted maxillary incisors were treated endodontically and decoronated 2mm above the cementoenamel junction and divided into three experimental groups based on the type of luting cements used. In group A glass ionomer cement, group B resin modified glass ionomer cement and in group C variolink II was used for cementation of pre fabricated post. Fracture resistance of the restoration was measured by applying loads at an angle of 135°. Results: fracture modes of all the samples were recorded and analyzed using mean and standard deviation. Inter and intragroup comparison was done using one way ANOVA test and Tukey HSD test. A statistically significant result was obtained between the three groups. Conclusion: An effective and significant observation was obtained when three groups were compared. Much higher results were obtained in group C where etched luting cement was used.
