Background: Complete sealing of the apical and coronal part of the root canal is the key to successful endodontics. One of the newer techniques utilizing thermoplasticized gutta-percha is Obtura II. Hence; we planned the present study to assess and compare the efficacy of obtura II and lateral condensation obturating techniques. Materials & methods: The present study included assessment of efficacy of two different obturating techniques. A total of 100 extracted human permanent anterior maxillary single rooted teeth were selected for the present study. The anatomical crown of each tooth was resected. In the wake of resecting, the roots were covered with polish paint, after the second layer of polish paint gets dried, the roots were put away in typical saline. The working length was controlled by setting a k-type file till it was quite recently observed at the apical foramen and afterward 1mm was subtracted from this length. The teeth were classified in to 2 groups of 50 teeth each. First group comprised of specimens in which lateral condensation technique was used while the other group comprised of specimens in which Obtura II technique was used for obturating the root canal space. Spectrophotometric Analysis was accomplished using light spectrophotometry. All the results were analysed by SPSS software. Results: In lateral condensation group and Obtura II group, the mean micro-leakage was found to be 0.0256 and 0.0240. Non- significant results were obtained while comparing the mean microleakage in between the two study groups. Conclusion: In terms of micro-leakage, both the obturating techniques show non- significant difference.
Key words: Lateral Condensation, Obtura II, Obturation.
