Comparison of human pulp tissue dissolution capacities of different irrigating solutions: An in vitro study

Abstract

Background: Organic tissue dissolution is considered as one of the most important and desirable property of endodontic irrigant, any soft tissue remnant, harboring bacteria, left in the canal after endodontic therapy may be the cause of failure. Aim: The present study aimed at assessing and comparing the human pulp dissolution (thereby eliminating the bacteria) capacity of some potential endodontic irrigants viz., sodium hypochlorite (NaOCl) (2.5% and 5.25%), chlorine dioxide (5%) and peracetic acid (5%). Materials and Methods: Forty human pulp specimens from extracted premolars were taken and weighed. They were immersed in test solution for 30 min, dried on filter paper and weighed again. The percentage weight loss was calculated and statistically analyzed. Conclusion: It can be concluded that NaOCl showed the best tissue dissolution capacity, followed by 5% peracetic acid.
