Evaluation of dissolution of pulp by sodium hypochlorite when mixed with tetrasodic etidronate and disodic ethylenediamine tetraacetate under controlled flow

Abstract

Background: Sodium hypochlorite serves as the most efficient root canal irrigating fluid. Objectives: This study's goal was to assess the replenished NaOCl's capacity to dissolve the tissue of pulp when combined with 9% tetrasodic etidronate (Na4HEBP), 18% tetrasodic etidronate (Na4HEBP), and 17% disodic ethylenediaminetetraacetate (Na2EDTA) under continuous controlled administration. Materials and Methods: Hundred and twenty complete undamaged teeth of the anterior mandible extracted due to periodontal problems within forty-eight hours were taken as a source of the pulp tissue. Results: It was found that there was a decrease in the weight of pulp tissue in all groups except negative control. Conclusion: NaOCl's potential to dissolve tissue with chelating agents like EDTA and HEBP inside the root canal was unaffected when there was controlled administration of EDTA and HEBP.
