Comparative evaluation of sealing efficacy of Thermafil and Obtura II obturating techniques- An in- vitro study
Syed Yasir Qadiri

Background: Success of root canal therapy depends upon the accuracy by which, its component steps are being performed. Hence; we planned the present study to assess and compare the efficacy of obtura II and Thermafil obturating techniques. Materials & methods: The present study included assessment of efficacy of two different obturating techniques. We analysed a total of 80 extracted single rooted maxillary incisors and resected their anatomic crown portions. Polishing and painting of the root was done followed by drying. Storing of the tooth specimens was done after biomechanical preparation and was divided into two study groups with 40 teeth in each group. One group comprised of specimen in which obturation was done by Obtura II technique while the second group comprised of specimens in which Thermafil technique was used. Spectrophotometric Analysis was accomplished using light spectrophotometry. All the results were analysed by SPSS software.  Results: The mean microleakage in the thermafil group was found to be 0.0245 while the mean microleakage in the Obtura II group was found to be 0.0020 respectively. We observed significant difference while comparing the mean micro-leakage in the specimens of both the study groups. Conclusion: Significant difference exists in between the obtura II and Thermafil obturating technique, in terms of mean micro-leakage.
Key words: Lateral Condensation, Obturation, Thermafil
