This study compares the apical sealing efficacy of three obturation techniques. Lateral condensation is taken as the standard and Obtura II and Gutta Flow 2 is compared with it. Aims and Objectives: To compare the apical sealing ability of Thermoplasticized (Obtura II), Single cone (Gutta-Flow 2) and cold lateral condensation. Materials and Methods: Sixty mandibular premolars were randomly divided into three groups for three types of obturation techniques. Group I: Cold lateral condensation (n=20), Group II: Obtura II (n=20), Group III: Gutta-Flow 2 (n=20). Roots were placed in 2% methylene blue dye for 72 hours. All the roots were sectioned longitudinally with a diamond disc under continuous water-cooling. Both surfaces were then directly examined under a stereomicroscope at 20X magnification. The linear extent of dye penetration was measured in millimeter from the apical end of the preparation. Results: Group I showed the maximum dye penetration when compared with Group II and Group III and the difference was statistically significant. Conclusion: Gutta-Flow 2 when used in combination with Guttapercha cone has the good apical sealing ability and shows promise as an obturation technique.
