| Background: This study aimed to evaluate and compare the apical microleakage of roots canal filled with cold lateral condensation of gutta-percha, cold lateral condensation of Resilon, Thermafil and RealSeal1 bonded obturation. Materials and methods: Sixty freshly extracted maxillary first molars with straight palatal roots .Using diamond disc bur with straight hand piece and water coolant the palatal roots of teeth were sectioned perpendicular to the long axis at the furcation area. All roots were prepared with crown-down technique using hand ProTaper system (Sx-F4).The prepared roots randomly divided into 4 groups of fifteen roots each; the groups obturated with different obturation technique. In Group 1 roots obturated with( lateral condensation of gutta-percha), Group 2 was obturated with(lateral condensation of Resilon),group3 was obturated with (Thermafil) while in group4 obturated with( RealSeal 1 bonded obturation).All the samples sealed coronally and stored in normal saline at 37°C for one week ,then all the roots submerged Indian ink for one week. The roots were cleared and the degree of linear dye penetration was measured in millimeter by stereomicroscope under 40X magnification with calibrated scale ocular grid. Results: The results showed that the RealSeal1 bonded obturation leaked apically significantly higher than other test groups, while the group of lateral condensation of gutta-percha exhibited the least value of apical microleakage. Conclusion: The complete hermetic apical seal cannot be created neither with gutta-percha nor with Real Seal 1bonded obturation | ||
