ABSTRACT
BACKGROUND:
Effective removal of smear layer ensures better penetration of irrigants ensuring root canal disinfection and has the potential of sealing dentinal tubules during obturation.AIM:
The aim of this study is to evaluate the canal cleaning efficacy and calcium ion liberation with the use of demineralizing irrigants, namely, 17% ethylenediaminetetraacetic acid (EDTA), 7% maleic acid, and 10% citric acid with or without ultrasonic (US) activation. MATERIALS ANDMETHODS:
Crowns of 62 extracted maxillary central incisors were decoronated and root canals prepared. Based on the final irrigant teeth were divided into following groups (n = 10), namely, 10% citric acid, 7% maleic acid, 17% EDTA, and 10% citric acid with US activation, 7% maleic acid with US activation, and 17% EDTA with US activation. Irrigants were subjected to inductively coupled plasma-atomic emission spectroscopy followed by debris scoring and scanning electron microscope analysis. STATISTICALANALYSIS:
One-way analysis of variance with the Bonferroni's correction for multiple testing was employed.RESULTS:
About 10% citric acid with US activation liberated the highest calcium ions and removed the maximum smear layer.CONCLUSIONS:
Citric acid with US activation is a potentially effective irrigation regimen with sodium hypochlorite.
