Title

AN IN VITRO COMPARISON OF CORONAL MICROLEAKAGE OF THREE ORIFICE BARRIERS FILLING MATERIALS

Pages

  156-160

Abstract

 Introduction: A coronal barrier in root-filled teeth is one of the most effective methods for prevention of coronal MICROLEAKAGE. The aim of this study was to compare coronal MICROLEAKAGE of three materials [light-cured GLASS-IONOMER (GI), mineral trioxide aggregate (MTA), and COMPOSITE RESIN] as coronal barriers.Materials and Methods: A total of 188 intact maxillary incisors were used. After instrumentation, all the canals were obturated with gutta-percha and lateral condensation technique using AH26 sealer. Then, the teeth were sectioned just apical to the cemento-enamel junction. The roots were randomly assigned to three experimental groups (n=56) and two negative and positive control groups (n=20). After placing the orifice barrier, the samples were immersed in 2% methylene blue solution for 2 weeks at 37oC. Then the teeth were longitudinally sectioned mesiodistally and dye penetration was measured under a stereomicroscope at ×10 magnification. Data were analyzed with one-way ANOVA and a post-hoc Tukey test.Results: The positive control group leaked significantly more than all the experimental groups (P=0.001). MTA exhibited less leakage than composite and GI (P=0.002) but no significant differences were found between GI and composite groups.Conclusion: Immediate placement of a suitable intra-orifice barrier like MTA, before final restoration, may help minimize recontamination of the remaining apical gutta-percha.
