Abstract
Background: To evaluate different irrigation systems for removal of intracanal medicaments.Materials & Methods: A total of 40 freshly extracted mandibular premolars were enrolled. The teeth were longitudinally split into two halves and debris were removed. The two halves were then reassembled and filled with Ca (OH)2 and were divided into four groups. The amount of residual Ca (OH)2 was calculated. The results were analysed using SPSS software. Results: The mean amount of Ca (OH)2 remaining was highest with respect to Group I followed by Group II and Group III. The lowest was seen with Group IV. Conclusion: CanalBrush and ultrasonic techniques were significantly better than the other irrigant groups.
