Evaluation of apical microleakage-using new polydimethylsiloxane-gutta percha based material: An invitro study

Abstract Objective The purpose of this study was to evaluate the apical micro leakage of Gutta Flow system as a sealer and complete obturating material and compare it with cold obturation technique using stereomicroscope. Methods 45 freshly extracted single rooted premolar teeth were collected and sectioned at the CEJ. The teeth were randomly divided into groups of 15 each and obturated as follows. GROUP A : Canals were obturated with Gutta Flow as obturating material. GROUP B : Canals were obturated with gutta percha cones and Gutta Flow as sealer. GROUP C: Canals were obturated with gutta percha cones and zinc oxide eugenol as sealer. Longitudinal sections of each specimen were done & methlylene blue dye penetration was evaluated to measure microleakage-using stereomicroscope. Results The data was analyzed using Unpaired ‘t’ test and Anova at 5% level of significance, showing significant differences among the 3 groups (p  . Conclusion Group B showed least leakage followed by Group A. Group C showed maximum leakage.
