The role of irrigation in root canal treatment is crucial; sodium hypochlorite is the most commonly used irrigant. Many methods were used to potentiate sodium hypochlorite, one of which is heating of the irrigant. Negative pressure irrigation is a new method of irrigation that was introduced to deliver the solution through the whole root canal length. Sixty single rooted teeth were used in this study. A total of 360 simulated lateral canals were created, 6 in each tooth, with 2 lateralcanals at 2, 4.5 and 6 mm of working length. To resemble the clinical situation, a closed system was created by coating each root with soft modeling wax. Roots were then randomly assigned to 3 experimental groups: group 1 (n
