Abstract

This study aimed to evaluate the accuracy of Root ZX in determining working length in presence of normal saline, 0.2% chlorhexidine and 2.5% of sodium hypochlorite. Thirty extracted, single rooted, single canal human teeth were used. Teeth were sectioned at CEJ and actual canal length determined. Then working length measurements were obtained with Root ZX in presence of normal saline, 0.2% chlorhexidine and 2.5% NaOCl. The working length obtained with Root ZX were compared with actual canal length and subjected to statistical analysis. No statistical significant difference was found between actual canal length and Root ZX measurements in presence of normal saline and 0.2% chlorhexidine. Highly statistical difference was found between actual canal length and Root ZX measurements in presence of 2.5% of NaOCl, however all the measurements were within the clinically acceptable range of ± 0.5mm. Overall Root ZX measurements were within 0.5mm of the actual canal length 100% of the time. The results of this study indicate that the Root ZX accurately determine the working length even in presence of intra canal irrigating solutions.
