Materials and Methods: Forty-five extracted human mandibular premolars with a single canal, extracted for orthodontic reasons, were stored in saline. Access cavity was prepared with endo access bur and pulp extirpations were done. The teeth were randomly divided into five groups of 9 teeth each. In group 1 and group 2 cleaning and shaping of the root canal was done using protaper file system and Hyflex system respectively. In group 3 and 4 obturation was done using Step-One obturation system and Calamus Dual respectively. In group 5 post space preparation was done using peeso reamers. Each sample tooth was embedded in alginate contained in Eppendorf tube. Tooth was placed in water bath with the two thermocouples attached at the apical and middle third which was in turn attached to thermometer. The rise in temperature was noted at the desired level and statistical analysis was done. Results and Conclusion: The mean temperature rise at the middle third for group 1, 2, 3, 4, 5 was 0.4°C, 0.15°C, 1.80°C,10.33°C, 9.46°C respectively. The mean temperature rise at the apical third for group 1, 2, 3, 4, 5 was 0.08°C, 0.08°C, 1.20°C, 6.91°C, 6.4°C respectively. ANOVA showed significant difference in mean temperatures of different methods. post hoc test comparison using Duncan's test revealed maximum rise in temperature during obturation using Calamus dual (Group 4).
