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 < 0.05).Conclusion: Group B showed least leakage followed by Group A. Group C showed maximum leakage.
