An In-Vitro Evaluation of Sealing Ability of Real Seal Using Fluid Filtration

INTRODUCTION: The aim of this study was to compare the sealing ability of Real Seal (RS) and Gutta-percha (GP). MATERIALS AND METHODS: Forty nine extracted human maxillary central incisors were used. The coronal part of each tooth was removed, the root canal was prepared using the crown down technique and apical enlargement to rotary file # 40. The specimens were randomly divided in to 3 groups of 15 each and two control groups of 2 each. Group 1, was obturated with RS and group 2 and 3 were obturated with GP and AH26 sealer by lateral condensation technique. In group 1 and 3 the smear layer was removed by 5mL of 5.25% NaOCl and 3mL of 17% EDTA. Leakage of the obturated roots was measured using the fluid filtration technique. This method was done at 2 min intervals for 8 min. data were analyzed using ANOVA and Tukey tests. RESULTS: Statistical analysis indicated significant differences between groups 2 with 1 and 3. The most leakage value was observed in the group 2. CONCLUSION: Root canal filling with RS or GP in combination with smear layer removal showed better sealing. Therefore the smear layer has more effect one apical leakage than the obturation system.
