description INTRODUCTION: Irrigation plays an indispensable role in removal of tissue remnants and debris from the complicated root canal system. This study compared the human pulp tissue dissolution by different concentrations of chlorine dioxide, calcium hypochlorite and sodium hypochlorite. MATERIALS AND METHODS: Pulp tissue was standardized to a weight of 9 mg for each sample. In all,60 samples obtained were divided into 6 groups according to the irrigating solution used- 2.5% sodium hypochlorite (NaOCl), 5.25% NaOCl, 5% calcium hypochlorite (Ca(OCl)(2)), 10% Ca(OCl)(2), 5%chlorine dioxide (ClO(2)) and 13% ClO(2). Pulp tissue was placed in each test tube carrying irrigants of measured volume (5ml) according to their specified subgroup time interval: 30 minutes (Subgroup A) and 60 minutes (Subgroup B). The solution from each sample test tube was filtered and was left for drying overnight. The residual weight was calculated by filtration method. RESULTS: Mean tissue dissolution increases with increase in time period. Results showed 5.25% NaOCl to be most effective at both time intervals followed by 2.5% NaOCl at 60 minutes, 10%Ca(OCl)(2) and 13% ClO(2) at 60 minutes. Least amount of tissue dissolving ability was demonstrated by 5% Ca(OCl)(2) and 5% ClO(2) at 30 minutes. Distilled water showed no pulp tissue dissolution. CONCLUSION: Withinthe limitations of the study, NaOCl most efficiently dissolved the pulp tissue at both concentrations and at both time intervals. Mean tissue dissolution by Ca(OCl)(2) and ClO(2) gradually increased with time and with their increase in concentration.
