Aim: The aim of this study was to evaluate the precipitate and its thickness formed by interaction between 5.25% sodium hypochlorite and 2% chlorhexidine and its prevention by using 18% etidronic acid and 99% absolute alcohol.
Methodology: 30 single rooted human extracted teeth were used. Following cleaning and shaping, all teeth were decoronated and divided into one 3 groups with 10 teeth in each group. All canals of teeth were irrigated with 5.25% sodium hypochlorite and 2% chlorhexidine. As control Group, in group A saline was used as intermediate flush. In experimental groups, group B and group C, 18% etidronic acid and 99% absolute alcohol was used as an intermediate flushes respectively.
Statistical Analysis:- one way variance of analysis and Tukey's test was used.
Results: Group A and B samples showed significant concentration of precipitate respectively. Group C showed less evidence of precipitate.
Conclusion: Within the limitation of this study, it was observed that 99% absolute alcohol had better efficacy in the prevention of orange brown precipitate when compared to 18%etidronic acid.
Key words: Root canal space, sodium hypochlorite, chlorhexidine.
