Objective: This study investigated intracanal heat changes when the EDDY sonic activation system was used for different durations.
Materials and Methods: Sixty (15 per group) maxillary canine teeth were used in this study. Teeth were decoronate and enlargedup to the T-endo must M40 file. Three thermocouples were inserted on the tooth: one at the apical foramen (T1), one at the workinglength (WL) of -5 mm (T2), and one at the WL of -10 mm (T3). A fixed setup was established, and an irrigation solution insidetheroot canal was activated for 10 (S10), 20 (S20), 30 (S30), and 60 (S60) seconds per group with an EDDY tip.
Results: The S10 group exhibited less temperature change and the S60 group demonstrated a statistically significant temperatureincrease.
Conclusion: Prolonged activation durations resulted in a greater temperature increase due to root canal dry out. This temperatureis more likely to transmit periodontal tissues than the increasing effect of sodium hypoclorite because of the scattered solution. Shorter activation durations with more sicluses would be more beneficial.
