Purpose: To compare the effectiveness of sodium hypochlorite 5,25% alone and ultrasonically activated on the calcium hydroxide dressing elimination from simulated lateral canals.
Material and methods: An experimental, in vitro study with 24 recently extracted single root human teeth were created simulate lateral canals and instrumented to the working length, each tooth was filled with a calcium hydroxide paste and incubated at 37ºC, 100% humidity for seven days. Teeth were randomly divided in to groups, in group 0 the dressing was removed using sodium hypochlorite irrigation and master file, and group 1 the dressing was removed using sodium hypochlorite irrigation and a # 15 activated U file during one minute. Both groups were obturated using termomechanical compaction. Postoperative radiographs were taken and evaluated; data were analyzed statistically using Mann Whitney or T student and chi square test.
Results: No statistically significant differences were found between both groups 0 and 1.
Conclusions: The sodium hypochlorite 5.25% alone or activated with ultrasound don’t remove completely dressing of hydroxide of calcium of simulated lateral canals of small diameter.
