Abstract


Objectives: Ca(OH)2 is widely used as an intracanal medicament. Removal of Ca(OH)2 dressing and the cleanliness of root canal walls before root canal filling are critical and can affect the outcome of the treatment. Aim of this study was to evaluate the efficiencies of Peracetic Acid (PAA) and other irrigating solutions in removal of Ca(OH)2 from the root canal. Methods: Twenty four freshly extracted maxillary incisors with straight roots and single canals were prepared with ProTaper system. The canals were filled with Ca(OH)2 paste. Specimens were randomly divided into 3 experimental groups (n=6). Positive and negative control groups were used. Group 1 used 2.5 ml 17% EDTA, group 2 used 2.5 ml 2.5% NaOCl + 2.5 ml 17% EDTA and group 3 used 2.5 ml 1% PAA. The specimens were evaluated with scanning electron microscope analysis and scored. Kruskal-Wallis and Student Newman-Keuls post hoc tests were used for statistical analysis. Results: In the apical and coronal thirds, 1% PAA was superior to the other groups (P<.05). In the middle thirds, no significant differences were found among the groups (P>.05). Conclusion: According to findings of the present study, 1% PAA could be strongly recommended for the removal of Ca(OH)2 from the root canals.
