ABSTRACT
Aim- Aim of this study was to assess the interaction between calcium hypochlorite and other commonly used irrigants like 2% chlorhexidine 17%EDTA and 10% citric acid for precipitate formation. Materials and methodology-Thirty single rooted tooth were selected for the study and were decoronated 1mm below the CEJ. Working length was determined and tooth were instrumented till F3.After instrumentation samples were devided into 3 group. In group A irrigation was done with 5 ml of CaOCL and 5 ml of 2%CHX. In group B , 5 ml of CaOCL and 5ml of 17% EDTA and in group C 5ml of CaOCL and 10% citric acid. Samples were subjected to stereomicroscopic evaluation for assessment of precipitate formation at coronal, middle and apical third. Data obtained were subjected to statistical analysis. Results-Group 1 showed orange brown precipitate which is concentrated on the coronal one third. Group 2 showed least precipitate formation among all the groups. Conclusion-Interaction of calcium hypochlorite with chlorhexidine produced orange brown precipitate. Significantly less precipitate formed with 17%EDTA and citric acid.
