Effect of 5% Calcium Hypochlorite on Mechanical Properties of Root Dentin: An in vitro Study

Abstract

Introduction: The aim of this study was to compare in vitro the effect of 5% calcium hypochlorite [Ca(OCl) Materials and methods: The available chlorine concentration of each solution was determined using iodometric titration. Standardized planoparallel dentin bars (n= 20) were divided into two test groups and one control group. The control, group 1, consisted of dentin bars stored in normal saline. The dentin bars in the two test groups were treated by exposure to following solutions: Group 2 to 5% Ca(OCl) Results: Available chlorine concentration was 64% in both the test solutions. There was a significant reduction in the flexural strength of 5% NaOCl group compared to 5% Ca(OCl) Conclusion: Within the limitations of this study, 5% NaOCl reduced the flexural strength and modulus of elasticity of root dentin bars more when compared to 5% Ca(OCl) How to cite this article: Reddy P, Balla S, Raghu SS, Velmurugan N, Gupta GT, Sahoo HS.
